RHEL: Why is there an additional domain name being added to the fqdn in the DNS request
Issue
The system is appending an additional domain name string to the name being resolved and the name resolution then fails.
$ tshark -r trace.cap -Y "dns.id == 0x8941"
161 538.904383 172.16.1.10 -> 10.100.10.5 101 Standard query 0x8941 A HOST.SubDomain.Domain.Domain
162 538.904705 10.100.10.5 -> 172.16.1.10 152 Standard query response 0x8941 No such name
