The host command resolves names put ping does not

Latest response

In what universe does this makes any sense? The DNS server at 10.10.10.11 is good. I'm resolving names with it right now to post this question. I can do host and it resolves to what I expect. But ping always returns unknown host.

[root@www network-scripts]# host infradc2012.infrasupport.local
infradc2012.infrasupport.local has address 10.10.10.11
[root@www network-scripts]# ping infradc2012.infrasupport.local
ping: unknown host infradc2012.infrasupport.local

OK, the above didn't come from RHEL. It came from a Fedora 21 RHEV 3.5 virtual machine in a RHEV 3.5 environment I cloned. After cloning, I updated ifcfg-eth0 with its new MAC address and a new IP Address. What I don't get is why does ping resolve addresses differently than the host command?

thanks
