I can ping to the other server using db1a instead of the host name.

By 'host name' I assume you mean IP address. db1a
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
# Auto-generated hostname. Please do not remove this comment. db1b.domain.com localhost db1b localhost.localdomain

db1b:~$ ping db1a PING db1a ( 56(84) bytes of data. 64 bytes from db1a ( icmp_seq=1 ttl=64 time=0.252 ms 64 bytes from db1a ( icmp_seq=2

So db1b's host resolution appears to be ok.  Is this output from db1a, or db1b?  It appears to be db1b, but your last issue was with db1a resolving db1b's IP address.

Cassandra doesn't do anything magical with hostname resolution, it relies on the underlying system for that.
