Jackson wrote, > What's the difference between a subnet and a network segment? A 'segment' almost always refers to a physical partitioning of a network. Typically, on an Ethernet network, a segment is any portion separated from another by a brigde, router, hub, switch, etc. The term 'subnet' is a bit more nebulous. Someone may refer to a physical segment as a subnet, but I would say it is more proper to speak of subnets only when you are discussing routing. That is, whereas several segments of an Ethernet might be connected in a switch, they must be one subnet since there is no routing. Or in other words, segments are how you breakup an Ethernet, subnets are how you breakup an IP network. My $0.02 -- Crist J.
