Now the basic question that might arise in one’s mind would be why do we need multiple IP hosting and why can’t we hold on to one single IP address? Well there would be two solid reasons why one would need multiple IP addresses and the first and foremost would be volume management. When a huge volume of data is to be sent each day and each one of them is acutely time sensitive, then one has to opt for multiple IP addresses to deliver the best and timely service.
The Second reason would be to have multiple channels or mail streams. When your company is really huge and a lot of departments exist it is mandatory that you hold multiple IP’s in order to channelize all the data properly and to the exact receiver end. This in fact maintains proper host and receiving ends and thereby avoids lots of confusion.
