The built-in Network & Internet Diagnostic & Repair Tool is another tool that you may want to have a look at.
Netstat (Network Statistics) is a command-line tool for monitoring and troubleshooting computer network issues. This tool shows you all your device’s connections in as much detail as you need.
With Netstat, you can view all your connections and their ports and stats. This information is valuable when setting up or fixing your connectivity. This article will introduce you to the Netstat command and the main parameters for filtering information displayed about your connections.
We’ll explore the following courses in this section:
- How to use the Netstat command.
- Use netstat parameters to filter connection information.
- Combining Netstat parameters.
Join me as we go through the above courses to help you better understand this tool and learn how to use it to troubleshoot your network issues.
1] How to use the netstat command
Click on the Start button and search for Command Prompt. Open Command Prompt with elevated privileges by right-clicking on it and selecting the Run as administrator option.
You can open Netstat by typing the following command and pressing ENTER:
netstat
You may not understand what the columns mean if you’re new to networking.
- Proto: The network protocol. It could be either TCP or UDP.
- Local Address: The IP addresses and ports of your computer’s network interfaces for the given connections.
- Foreign Address: The IP addresses and port names of the remote devices.
- State: Indicates the state of the connection. For example, find out active and closed connections.
The netstat command shows you your active connections and their details. However, you’d notice that the foreign address column prints the IP address and port names.
To show the connections’ port numbers instead of the port names next to the IP addresses, use the following command:
netstat -n
Further, the system can disconnect or connect to networks, and the network details can change at intervals. Hence, we can use the following command to refresh the netstat network details at intervals using this command:
netstat -n 5
To stop the refreshing, press the CTRL + C key combination.
NOTE: The 5 in the command above refreshes the command every 5 seconds. If you wish to increase or shorten the interval, you can modify this value.
2] Use netstat parameters to filter connection information
The netstat command is a powerful command that can show you every detail about your device’s connections. Explore the most commonly used netstat parameters to find specific network details.
- Display active and inactive connections
Show the networks that are active or inactive.
netstat -a
- Display applications information
List all applications that are associated with the connections.
netstat -b
- View network adapter stats
Show statistics on incoming and outgoing network packets.
netstat -e
- Display foreign addresses’ fully qualified domain name (FQDNS)
If you don’t want to see the port numbers or names, the following netstat parameter will show your foreign addresses’ fully qualified domain names.
netstat -f
- Show port numbers instead of names
Change the foreign address port names to port numbers.
netstat -n
Similar to netstat, and it has an extra column for every connection’s Process ID (PID).
netstat -o
- Filter connections by protocol
Display the connections for the protocol you specify – UDP, TCP, tcpv6, or udpv6.
netstat -p udp
NOTE: You should change the udp part to the protocol whose connections you want to view.
- View non-listening and listing port
Show connections and their listening and bound non-listening ports.
netstat -q
Categorize networks by available protocols – UDP, TCP, ICMP, IPv4, and IPv6.
netstat -s
Show the routing table of your current network. It lists every route to the destination and matrix available on your system. Similar to the route print command.
netstat -r
- Display offload state connections
Show a list of connection offload states of your current connection.
netstat -t
- See NetworkDirect connections
Shows all NetworkDirect connections.
netstat -x
- Display connection Templates
Show your networks’ TCP connection templates.
netstat -y
3] Combining Netstat parameters
You can further filter the Netstat parameters to show you information about your connections any way you want. From the above commands, you only have to add a second parameter to show a combined view.
For instance, you can combine the -s and -e parameters to view the statistics for every protocol. This way, you can combine other parameters to get the desired results.
When mixing multiple Netstat parameters, you don’t need to include two dashes (-). You can use one dash (-) and append the parameter letters without a second one.
For example, instead of typing the following command:
netstat -s -e
You can write it as:
netstat - se
If you forget the parameters, a quick way to remember them is by asking netstat to help. Simply run the following command:
netstat /?
To stop the netstat query process, press the CTRL + C key combination.
Can we check network connectivity using netstat?
We can check network connectivity using the netstat or network statistics command. This allows us to see active network connections and their status. The tool can view incoming and outgoing network connections, routing tables, port listening, and usage statistics. This command can be handy for network administrators when troubleshooting network issues. By understanding how to use this command, you can quickly and efficiently diagnose problems with your network.
How do I see network issues in Windows?
You can check your network connection status in Windows quickly and easily. Select the Start button to do so and type “settings” into the search bar. Once you’re in the Settings menu, select “Network & internet.” The status of your network connection will be displayed at the top of the page. If you’re having trouble connecting to the internet, this is a helpful first step in troubleshooting the issue. You also check quickly, and if you see the wifi icon missing, you have a network issue.

- Shiba Inu’s Shytoshi Kusama said that Layer 2 solution Shibarium testing phase will end on Wednesday.
- Shibarium developers attributed initial network and bridge problems to high demand.
- The relaunch will include additional validators for earning staking rewards on BONE tokens.
Shiba Inu’s Layer 2 scaling solution Shibarium suffered a roadblock on its mainnet launch. Problems with the network left around 1,000 Ethereum and 600,000 BONE tokens locked, leaving users unable to access or recover their funds and pushing down Shiba Inu’s (SHIB) price.
Shytoshi Kusama, leading developer of the Shiba Inu project, attributed the technical problems to high demand and announced a $2 million insurance to cover the value of the tokens paused on the Shibarium bridge. Since then, Kusama has shared new updates on Shiba Inu’s progress in recovering the Layer 2 project and preparing it to go live once again.

Shibarium close to the end of testing phase
According to the latest update from the Shiba Inu community published Tuesday, the ecosystem’s Layer 2 scaling solution has nearly completed its testing phase. After two days of tweaking different parameters, developers behind the blockchain consider that the system is enhanced and optimized.
The key challenge faced by Shibarium at its launch was a large volume of activity from users, according to Kusama. Since this was not anticipated, Shibarium’s operations were affected and user funds were paused on a bridge.
In the update, Kusama says that a new monitoring system and additional fail safes have been introduced in the Layer 2 blockchain. In the event that Shibarium faces a high level of user traffic again, the team is equipped to handle the situation.
Tomorrow [Wednesday] additional validators will go live, giving even more options for you to stake your BONE for a share of the rewards earned for these two roles in our society. Testing will wrap up, and we will prepare for public consumption once again
Kusama said in the blog post.
In addition to bringing Shibarium back, Kusama announced the launch of new validators to increase opportunities for BONE token holders to stake their assets and earn rewards.
The update failed to provide impetus to SHIB, which traded at $0.00000797 at the time of writing, a 0.13% fall compared with the previous day.
Bitcoin, altcoins, stablecoins FAQs
Bitcoin is the largest cryptocurrency by market capitalization, a virtual currency designed to serve as money. This form of payment cannot be controlled by any one person, group, or entity, which eliminates the need for third-party participation during financial transactions.
Altcoins are any cryptocurrency apart from Bitcoin, but some also regard Ethereum as a non-altcoin because it is from these two cryptocurrencies that forking happens. If this is true, then Litecoin is the first altcoin, forked from the Bitcoin protocol and, therefore, an “improved” version of it.
Stablecoins are cryptocurrencies designed to have a stable price, with their value backed by a reserve of the asset it represents. To achieve this, the value of any one stablecoin is pegged to a commodity or financial instrument, such as the US Dollar (USD), with its supply regulated by an algorithm or demand. The main goal of stablecoins is to provide an on/off-ramp for investors willing to trade and invest in cryptocurrencies. Stablecoins also allow investors to store value since cryptocurrencies, in general, are subject to volatility.
Bitcoin dominance is the ratio of Bitcoin's market capitalization to the total market capitalization of all cryptocurrencies combined. It provides a clear picture of Bitcoin’s interest among investors. A high BTC dominance typically happens before and during a bull run, in which investors resort to investing in relatively stable and high market capitalization cryptocurrency like Bitcoin. A drop in BTC dominance usually means that investors are moving their capital and/or profits to altcoins in a quest for higher returns, which usually triggers an explosion of altcoin rallies.

Those who tested positive for COVID-19 (confirmed by a PCR test) had an increased risk of mental illness, fatigue and sleep problems, finds a new study which analysed the electronic primary care health care records* of 226,521 people from across the UK between February 2020 and December 2020.
The research**, published in The Journal of the American Medical Association Network Open (JAMA Network Open) today, was funded by the National Institute for Health Research Greater Manchester Patient Safety Translational Research Centre (NIHR GM PSTRC). The Centre is a partnership between The University of Manchester and The Northern Care Alliance NHS Foundation Trust.
The study found there was an almost six-fold increase in the likelihood of reporting fatigue to a GP following a positive PCR test and a threefold increase in the risk of sleep problems compared to those without a positive test, for people who haven’t previously visited their GP for any of these reasons in the past.
There was also an 83% increase in mental illness following a positive PCR test. However, there was also a 71% increase in the risk of mental illness for people who received a negative PCR test compared to the general population. Researchers believe this throws some doubt about whether COVID-19 is directly causing mental illness, because it is clear that those who get a test are more likely to have risk factors for mental illness, for example pandemic-related anxieties.
Dr Matthias Pierce, researcher at The University of Manchester who led the work, said: “When we began this research project we wanted to investigate whether we could find any evidence in primary health care records that COVID-19 was linked to an increased risk of mental health illness, sleep and fatigue problems.
“While fatigue is clearly a consequence of COVID-19 the risk of experiencing sleep problems is also very high. However, we are sceptical regarding the extent that COVID-19 is directly causing people to become mentally ill, or whether those with a predisposition to mental illness are more likely to get tested.”
Professor Roger Webb, from The University of Manchester, who co-leads the Mental Health research programme at the NIHR GM PSTRC, said: “Our findings align with those generated by investigations conducted in other countries in revealing elevated risks of mental illness, self-harm, fatigue, and disrupted sleep patterns among people testing positive for infection during the pandemic. Establishing the mechanisms that have caused these outcomes to occur is the next major challenge for researchers in our field.”
Professor Carolyn Chew-Graham, a co-author on the paper, Professor of General Practice Research at Keele University and a General Practitioner, said “It is vital that general practitioners recognise the long-term impact of COVID-19 infection on their patient population. Offering follow-up to people who test positive for COVID-19 infection may help identify persisting symptoms, and sign-post people to the Your COVID Recovery website. The increased risk of developing mental health problems in people who tested negative may be due to health anxiety in these patients, and primary care has a role in identifying and supporting such patients.”
