ESPs typically do not offer this, because IP addresses aren't really easily individually portable like cell phone numbers are in the US.
Maybe one will pop up and say they can do this, but it would be the exception more than the rule. I've never heard of it being offered. And if it's not IP addresses you own, but IPs owned by the original ESP, then those IPs are surrounded on all sides by other clients and carving a routable range out is difficult to the point of being insurmountable. And it would be asking the ESP to give something up.
