They are, but they are not even using the amount of redundancy available by DNS today (read: "as many name servers as fit into a minimum sized UDP packet full of glue"). So there is hardly an argument for doing anycast. > Someday a bogon routeserver service like this one: > http://www.cymru.com/BGP/bogon-rs.html > might want to use anycast. The route servers use TCP, which will not work over anycast (in the general case - consider load balancing, every other packet going to a different destination machine. No problem for UDP, big problem for TCP) Gert Doering -- NetMaster -- Total number of prefixes smaller than registry allocations: 57882 (57753) SpaceNet AG Mail: netmaster at Space.Net Joseph-Dollinger-Bogen 14 Tel : +49-89-32356-0 80807 Muenchen Fax : +49-89-32356-299
