Everything You Need to Know About Chrome Net Internals DNS

One of the most frequent problems we run into as internet users while attempting to visit websites is the "DNS_PROBE_FINISHED_NXDOMAIN" error. The DNS (Domain Name System) query seems to have failed, and as a consequence, the browser was unable to find the IP address connected to the domain name, according to this error message. Such problems may be detected and fixed with the use of chrome://net-internals/#dns. We'll provide a thorough introduction to chrome://net-internals/#dns in this post.

Introduction to Chrome Net Internals DNS

Google Chrome has a tool called Chrome Net Internals DNS that lets users monitor and troubleshoot network activities, including DNS lookups. The log offers information on network requests, DNS lookups, and other network activity-related events.

Accessing Chrome Net Internals DNS

Simply enter "chrome://net-internals/#dns" in the address bar of your browser to access Chrome Net Internals DNS. By doing so, the DNS tab will open and provide a list of the browser's most recent DNS queries.

Understanding the Chrome Net Internals DNS Interface

The host resolver cache, DNS events, sockets, and spdy sessions are the four main divisions of the Chrome Net Internals DNS interface.

Cached host resolver

A list of every domain name that the browser has looked up is shown in the Host Resolver Cache section. The DNS record's TTL (time to live), which defines how long the DNS record will be cached until the browser does a new search, is also shown in this section.

DNS activity

The DNS events section displays all recent DNS queries made by the browser. Information like the domain name, the IP address of the DNS server that was used, the time of the request, and the outcome of the query are all included in this part.

Sockets

The Sockets section lists all active network connections that the browser has established as of the present moment. The local IP address, the distant IP address, and the connection status are all shown in this section.

Spdy Sessions

A list of all currently running Spdy sessions created by the browser is shown in the Spdy Sessions section. A protocol called Spdy is used to speed up online browsing.

Fixing DNS Issues with Chrome Net Internals DNS

The "DNS_PROBE_FINISHED_NXDOMAIN" error, which denotes a failed DNS lookup, is one of the most frequent problems customers encounter when surfing. Such problems may be detected and fixed with the use of chrome://net-internals/#dns

Use Chrome Net Internals DNS to troubleshoot DNS problems by doing the following steps:

Step 1: Type "chrome://net-internals/#dns" into your browser's address bar to launch the DNS tab.

Step 2: Verify that the domain name you're attempting to visit is listed in the Host Resolver Cache section. Check the TTL to see whether the record has expired if it is displayed. The next time you attempt to visit the website, the browser will do a fresh DNS query if the record has become invalid.

Step 3: Look through the DNS events section to check whether the domain name you're attempting to access has been the subject of any recent DNS queries. Check the search result to determine whether it was successful and if there have been recent queries. If the outcome is unsuccessful, there can be a problem with the domain name or the DNS server.

Step 4: If the DNS server is the problem, try switching your browser's DNS server. You may accomplish this by going to the network settings on your computer and altering the DNS server address. You may also use a public DNS server like Google DNS or OpenDNS.

Conclusion

A useful tool that may assist in the diagnosis and resolution of network problems, particularly DNS problems, is Chrome Net Internals DNS. The tool offers thorough details on DNS queries, network requests, and other network activity that may be used to spot problems and solve them.
