Ravi,
Unfortunately that list of IP addresses or any DNS entries are not stored within the ALM DB to reference too. In order to be able to have that connection name resolve to an IP address it would have to have a list of hostnames to resolve against. That is what your DNS table does, and unfortunately no table is maintained within ALM nor is there a connection to the DNS server to query the host name and resolve to the IP address. This functionality just is not there.
The best I can off you is to contact your support provider for ALM and ask that a Enhancement Request be submitted to add such functionality in a future release version or patch, as currently this functionality does not exist within the ALM functionality.
Hope this helps,
Dan
