Hi Guys,

Just wondering when subnet mask are actually needed... Just that I noticed that some people have (internal) IP addresses of 10.x.x.x but have 255.255.255 subnet masks and sometimes people have the right subnet mask of 255.x.x.x. any ideas?

thanks guys

You're correct, and a subnet mask of 255.0.0.0 will allow millions! :D Note that many SOHO router products can only deal with a single class C network, so the subnet mask will normally be 255.255.255.0, which should suffice for most home uses. :)
