I have a friend who has a 1000GB + Foxtel package.
We were discussing how many PC's we could have connected (wirelessly or cabled) to the Telstra Gateway Max 2 at once.
I worked backwards and said:
10.0.0.0 assumed to be unusable
10.0.0.138 for gateway
10.0.0.255 for broadcast
Given a few IP's spare to be sure (say 10) => 255-10-3=242
Round off to 240 PC's!
Thats approx. correct I would say.
What do you think?
