Re: Multi-homing small ISP



You don't have to have your own IP space from ARIN to have another ISP
route your /24.  BGP handles this fine.  Just negotiate with the second
ISP to route the first ISP's IP's to you.  You may have to add your
information to the Route Arbiter database(s) for your new ISP to do it.
