First off I'm a cisco noob so I relialize I'm probably asking a rediculous question. I am currently setting up a UC540 that I bought used that does not have a configuration. The problem I have encountered is the router is capable of pinging IP addresses but is unable to ping domain names. Furthermore I am unable to access internet resources from my workstation that is directly connected to the router. The router is directly connected to my cable modem.
I started over again from scratch and only have what I believe to be the bare minimum in the config to get started. My current config is as follows:

I am experiencing similar issues in my envoironment, but for me the issue seems to be only 1 FQDN and only on 1 router in my network. When I ping time.nist.gov on this router it tries to resolve it to an ipv6 address which leads to the following:
router1#ping time.nist.gov
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2610:20:6F15:15::27, timeout is 2 seconds:
% No valid route for destination
Success rate is 0 percent (0/1)
But when I ping other sites:
router1#ping yahoo.com
Translating "yahoo.com"...domain server (10.1.253.10)
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 98.138.253.109, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 108/134/152 ms
I have ipv6 disabled over my entire network and this is the only device experiencing this. Where is this coming from?

Uriah,
Try the ping ip (host name) command instead of just ping.
If you want to ping an ipv6 host you use the ¨ping ipv6 (hostname)¨ command for ipv4: ping ip ...
Let me know how it went...

I know this post is old but there was no resolution I could see.
I recently solved this issue on an 1841 router by enabling (config)#ip domain-lookup
Hopefully this helps someone like me at some point.
