Currently, we have a T1 line and Comcast. The web traffic is mostly over Comcast while the email traffic is over the T1 line. We want to swap it. Is there an advantage to get multiple IP address through Comcast since the email and some web traffic will be over Comcast, or does it really not matter? Since we only have one Comcast line coming into our building, will multiple IP address help reduce the bandwidth somehow? Thanks, in advance, for your help. - Charles

from the sounds of it I wouldn't touch the thing at all! – tony roth Dec 3 '10 at 21:47
Sounds like you're getting rid of your T1... is that the case? (hard to tell from the way you asked the question) – l0c0b0x Dec 3 '10 at 22:11
well he did say swap, the reason I said don't touch a thing is because he doesn't know what he's doing! – tony roth Dec 3 '10 at 22:16
@tony - you can't assume that he doesn't know what he's doing with the information given. There may be a good reason he wants to swap the two circuits. – EEAA Dec 3 '10 at 22:19
Riiiight, he said 'swap' but then states that "the email and some web traffic will be over Comcast" (he could be referring to 'some traffic' as not having so much web traffic). I'll read the question a few hundred times more, maybe eventually it will make sense. – l0c0b0x Dec 3 '10 at 22:23

The number of IP addresses provisioned on a specific circuit has nothing to do with how much bandwidth is available.

I'm curious as to why you'd want to make this change. Unless your comcast connection is very slow (which I doubt), you're going to have much higher bandwidth available on that connection versus the T1. Unless your use case is much different than most places I've seen, web browsing will suck up a whole lot more bandwidth than email will.
