I've read on google map help pages that there is a limit of 15k calls to google maps per ip/day.
If I have two or more sites that use google maps and I have a different ip for each do you think google would regard that as cheating and possibly cancel their service, that they can at any time for any reason under their agreement?
I was thinking of doing this (buying seperate ip for each site) in case I would ever move or sell them.
A different IP is a different IP. If you were using 1 IP for www1.example.com and anither IP for www2.example.com, which are basically the same site, then it might start getting into a gray area. But different IPs for completely different sites should be no issue.
