Some outdated code is trying to reach a website that no longer exists.A security control blocked the site a user was trying to reach.User error mistyping a domain name in a browser.We’ve got an entire blog post devoted to what an NXDOMAIN response code means for your network, but we’ll touch on a few basics here. It’s essentially a way of saying that the query failed. The response that the server is sending back is, “Hey, you queried for this domain but that domain doesn’t exist or I don’t know that it exists.” Most of the remaining 10 to 15 percent of response codes received will be NXDOMAIN. DNS Response CodeĭNS query failed because the domain name queried does not existĭNS query failed because an answer cannot be givenĭNS query failed because the server refused to answer due to policy Being able to access web servers, even for them to tell you that you don’t have access, still means that you resolved that domain to the IP address. However, it would tell the user’s device, “Hey, actually, this is the domain you really want-and here’s the IP address for that domain.”įurthermore, if a user visits a website and the webserver fails or tells you you don’t have access, there would still be a NOERROR response in the DNS logs. The user would get a successful NOERROR response code for going to bluecat.ca.
We’ve purchased that domain and want to be sure they’re redirected to instead. Just because a NOERROR response was returned doesn’t mean a user on your network was taken to the website they specifically asked for.įor example, take a user who enters bluecat.ca. Great! But… It doesn’t always mean everything is perfect A user asked to go, and the resolver and DNS servers took it there. It’s a way of saying everything was OK, there were no issues with the query.

More than half of IT managers say that their network teams are overwhelmed with DNS tickets and service requests. Consequently, about 16 percent of DNS queries on their networks fail, resulting in one of the other three common codes. In surveys of our own customers, DNS queries successfully resolve about 84 percent of the time on their enterprise networks, generating the NOERROR code.
Many are rare and only appear in very unique circumstances.

Officially, the full list of response codes numbers more than two dozen. Furthermore, we’ll touch on how BlueCat’s platform can help you better monitor and track your response codes and network activity. Then, we’ll examine each of the four most common codes in depth. In this post, we’ll touch briefly on the full compilation of response codes, also known as DNS return codes.
Response data, particularly when there’s a problem, can you help you troubleshoot or identify a security breach faster. The four most common ones, returned with virtually all DNS queries, are NOERROR, NXDOMAIN, SERVFAIL, and REFUSED.īut do you really know what these common codes mean? Whether you successfully make it to the website or not, every response you get includes a code. And with the help of resolvers and DNS servers, that query gets a response.ĭNS translates human-readable domain names that we remember (like ) to the computer-friendly language of Internet Protocol (IP) addresses (like 104.239.197.100). To get there, your device sends out a DNS query. You want to visit a website, so you enter the URL in your browser. How well do you know your DNS response codes?ĭNS queries and responses are fundamental to how the internet works.
