If you read what Joe wrote, he doesn't currently have an AS number or employ BGP with his Internet providers. Extrapolate for his IPv4 assignment situation and the /24 announcement barrier. In an IPv4-depleted world, he won't be doing anycast any time soon, even if it was a sound plan.
Anyone having /24 can start hosting business with 255*N anycast servers.

I donÿÿt think thatÿÿs quite trueÿÿ I think you will find that 254*N is probably the best theoretical Max with just a /24 and that more likely, youÿÿll need some hosts on that subnet that donÿÿt necessarily provide anycast services bringing the practical limit somewhat lower. Of course, if you have what you need to do 255, you can probably actually do 256.
Advertise the /24, internally route 256 /32s to the devices that service those IPs on one or more networks numbered out of other IP ranges. The machines all need unique unicast IPs anyway. ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
