The Exchange 2010 environment I manage was stood up by a predecessor. One of the two Exchange servers in the environment uses four IPs all from a single NIC.
I'm trying to determine what each of these four IPs are used for and I'm not exactly sure how to find that information. Everything I can find is pointing to a URL and not an IP so I don't know how to determine what each of the IPs do.
Has anybody been in a similar situation before? What did you do to figure this out if there wasn't documentation explaining the reason for each of them?
Thanks in advance!
Edit: After running
netstat -an | findstr xxx.xxx.xxx.xxxI have these additional clues.
UDP - 137-138
TCP - 139 & random ports from 7xxx-55xxx
TCP: 443 & 3389
TCP: Random ports from 7xxx-60xxx
Additional Note: IP's #2 and #3 are bound to IIS but I can't find anywhere that states explicitly what one of them is used for vs. the other.
