Company with 2 IP addresses, which to use

Our company is in Greensboro, NC and has 2 static ip addresses allocated but they're on different networks.  I noticed recently after doing a trace ping that our default IP's first hop is in Wilmington, NC and the secondary/backup IP has a first hop a few miles from our office.  

After the first hop in Wilmington the packets come back to Greensboro and onward toward Alabama, and so on.  Both IP's have a 1ms ping and tracert time but I just wonder if it's best practice to use the more "local" IP as the default IP. So packet's round trip is at least slightly less.  

It may be a dumb question and may make no difference at all but I'm just curious.

it may be relative between the two IP addresses. One web site might be closer or less hop than the other, so it is very relative. or one client can reach you closer via one IP or the other.

are you using two different provider? are both public IP terminated to same device?

one thing you can consider is using load balancer to balance traffic out to both provider, this ensures you are fully utilizing both links without over subscribing one, but then again this depends on your need and application.

There is no real best practice for something like this (that I know of), but it doesn't make much difference.

Once it leaves your premise, the route it takes is completely dependent on the local ISP and their provider.  They could change routes at any time based on their needs or their own failover.

I wouldn't worry about it at all.

Both IP's are from the same provider.  

From what I can tell the hops take the same pattern for 90% of the internet traffic in this office so the default IP does take an extra hop in Wilmington before coming back to Greensboro and onward.

That's a good point though because I'm not sure if load balancing is setup.  We have our own Sonicwall Firewall/DG and the 2 boxes from the provider (Adtran 908e, and Adtran 908) are in the same room as our rack.  

Both IP's come from those 2 boxes and of course our Sonicwall has 2 interfaces designated IP1 and IP2.

Sounds like your provider is routing your 2 IPs differently, and likely to provide you with some redundancy in the event one site goes down or simply the way they route that subnet block.

If it was me, I wouldn't be concerned.

K.  I figured as much.  This is more of slow work day curiosity question. ;)
