I need to compare the Connection used by a DataSource against a set of DriverManager parameters to determine if they are "equivalent". I do this by comparing the hostname, datbasename, and port. My problem is that I am given the DriverManager parameter DNSname but when I retrieve the hostname from the DataSource Connection, I am given the TCP/IP address.
Can anybody tell me how to translate the DNSName into it's TCP/IP address so that I can compare on these properties?

To resolve the IP address to then DNS name, ping with the -a argument.
example: ping -a 64.78.181.41
If it can resolve the address, it will return:
Pinging tut.ejip.net
Of course, this doesn't work well the other way, as multiple DNS names can point to the same IP address.
Hope this helps somewhat.
