IP

what does default gateway really tell you? What do you need to look for to find the address that a firewall sits on, what does a subnet calculator do for you?

Re: IP

True, true!!The gateway is nothing more than a router, it is your route to the Internet from a LAN, or your route to another subnet from a LAN. It is usually your network IP portion with a 1 on the end, OR the first legal address in a subnet. For instance if your IP was 222.3.24.218, and you subnet mask was 255.255.255.0 then your default gateway is most likely 222.3.24.1. ]This will aslo help explain the subnet calculator. Change the aforementioned subnet mask to 255.255.255.192, and the first legal address changes. Now you are left with only 2 subnets on a class C addy.

222.3.24.65-128 (first subnet)

222.3.24.129-190 (second subnet)I don't use the calculator, I do it on paper, the calc doesn't help ya to really learn what your doing, it's just handy if you already know. Get a book on subnetting and supernetting. Just remember your IP is 4 octets of 8 bits.

128 64 32 16 8 4 2 1

1 1 1 1 1 1 1 1the ones are the bits each one represents a number above it. Therefore the number 32 looks like this in Binary 00100000, the number 255=11111111. Get it!Peace, BROM
