How Linux implements subnetting, as opposed to Solaris?

For Linux users, it might help if you briefly explained how Solaris implements subnetting – bbaja42 Jun 25 '11 at 23:18
LinuxJournal has an article on the topic, if that helps. – new123456 Jun 25 '11 at 23:53

I believe the netmasks in linux are set in /etc/sysconfig/network-scripts , on a per interface bases.

Where Solaris uses /etc/netmasks to over ride or set the expected netmask, this can be done with the netmask directive in the ifcfg-ethX script.
