Hostname not resolving to IP

Hello,

We have received error while /scripts/ipcheck

The hostname (server.domain.com) resolves to x1.x1.x1.x1. It
should resolve to x2.x2.x2.x2. Please be sure that the contents
of /etc/hosts are configured correctly, and also that there is a
correct 'A' entry for the domain in the zone file.


But we have modified the domain zone entries and /etc/hosts.

-------
root@ server  [~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
#::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
x2.x2.x2.x2  server.domain.com server
root@ server  [~]#

------

root@servidor [~]# hostname
server.domain.com 
root@servidor [~]# hostname -i
X2.X2.X2.X2
------

But while dig the hostname still the hostname has resolved to IP : X1.X1.X1.X1

root@servidor [~]# dig  server.domain.com  +short
X1.X1.X1.X1
root@servidor [~]#

Resolution :

This is because the resolver in /etc/resolve.conf was caching the old IP. I've changed the first resolver to 4.2.2.5 and now I get this while on the server

root@servidor [~]# dig  server.domain.com  +short
X2.X2.X2.X2
root@servidor [~]#
