Web Hosting Talk : Web Hosting Main Forums : Dedicated Server : 8 ip addresses (5 usable)

[sql]

When you order a server, usually it said 8 ip addresses (5 useable). What is it mean? What's the other three for?

[Joshua]

The other 3 IPs are used for the VLAN configuration.

The first one is your network address, the last one if your broadcast address and one of the other ones is used for your gateway.

I don't get it. Somebody care to explain more in detail? Thanks before hand.

This is as simple and lamens term as I can put it...

Network Address :
Your ISP divides each client into seperate subnets. In this case the subnet has 8 ip addresses which means a 255.255.255.248 or /29 network mask. You need 1 ip address to define this network. Minus 1 ip address.

Broadcast Address :
Every subnet needs a broadcast address. This is the ip address used to broadcast to all ip's in your subnet. Minus 1 ip address.

Default Gateway :
You need an ip address on your subnet that knows how to route traffic to destinations outside of your subnet. The default gaetway needs to be assigned an ip address in your subnet. Minus 1 ip address.

Total : 3 ip addresses
