There is absolutely no difference between receiving a 72 series IP and a 99 series IP. It will not make the slightest difference in performance.
The ONLY time this has mattered was when new IP blocks from bogon assignments were made (unused or assigned to someone else) ... the routings would get messed up because net admins were reluctant to change routings for bogon IPs until the new assignee signed in blood that the IP block was legitimately theirs!
ALL of Rogers Ontario connections route through Toronto, EVEN if you are connecting to a site in Ottawa. Yup it goes Ottawa -> Toronto -> Ottawa and all that does is add a few mS to the transit times. Barely enough to be noticeable.
Rogers has attempted to put geo-location information into the DNS databases for IP blocks, but that doesn't really mean anything. It's like your filling in a "Where are you from?" when visiting a museum for example ... you could write "Moon" and it wouldn't mean anything. The geolocation is sometimes helpful in locating where an IP is used, but for most large ISPs, it doesn't mean a lot.
Rogers IPs often state Toronto because that's where the head office is.
There are ways to get a new IP, but it won't make any difference in this situation, and there's no guarantee that you'll get to a different IP block.
Your typical Rogers front line tech won't have a clue as to how to release and therefore reassign you with a new IP number by clearing ARP tables.
