Hi, I am trying to understand the below terminology as in my company I used to hear this term from infrastructure team a lot..

What is VIP (Virtual IP), BIG IP and WIP (Wide IP) and Internet IP ? I have goggled a lot, but got only little information and unable to understand.

In above question, there are lot of IPs I am not sure it it is used interchangeably.

For Example: consider I am having load balanced server (2 servers - Server A and Server B)

Server A will have the BASE IP address like our PC/Laptop..similarly for Server B..

How this VIP, WIP involved?

Big IP and Wide IP may be terminology specific to the products that you are using. It may be a good idea to do a little bit of reading of the documentation that came with them.

A Virtual IP address, is just another IP address. It is generally called a Virtual IP address, or a VIP, because the address is not used to represent physical hardware. For example, you have bonded NICs -- and the VIP is the IP address for the bonded pair. Or another example, you are using VmWare, and the VIP is used on a virtual machines, which has a virtual NIC, etc.

All in all though, a VIP is just another IP address.
