Troubleshooting IPv4 DNS configuration
Symptom
After enabling dynamic domain name resolution, the user cannot get the correct IP address.
Solution
• Use the display dns host ip command to verify that the specified domain name is in the cache.
• If the specified domain name does not exist, check that dynamic domain name resolution is enabled
and that the DNS client can communicate with the DNS server.
• If the specified domain name is in the cache, but the IP address is incorrect, check that the DNS
client has the correct IP address of the DNS server.
Verify that the mapping between the domain name and IP address is correct on the DNS server.
