IPv6 DNS Non-authoritative answer
I support a large group of IT user who work remotely. I came across an issue that caused me a bit of grief, and I though I would try and understand the why a little better. We, like most companies, support a naming convention for our hosts and depend on internal DNS servers to connect us properly to the given system, but if are lazy and us the short name we get odd ip's returned. Example say all my servers in location 1 start with rrr and are in somewhere.com. Most user would know to use the FQDN, but I have one guy that just types in rrr . This problem came to my attention this week and I found the follow to be true. If our primary DNS has no entry for rrr hist, the request seems to be answered by the COX IPv6 DNS at either 2001:578:3f::30 or 2001:578:3f:1::30 and the following is returned: C:\Users\John>nslookup rrr 2001:578:3f::30 Server: cdns1.cox.net Address: 2001:578:3f::30 Non-authoritative answer: Name: rrr Address: 92.242.140.2 This only happens on the COX IPv6 DNS and the COX IPv4 DNS just time out. Now this address is not even close, and seems to be somewhere in Russia. Can someone explain why this might be happening?2.8KViews0likes4Comments
