IPv6:

ESnet provides full IPv6 service.

ESnet runs IPv6 native in the core backbone. ISIS and i-BGP are used as interior routing protocols and BGP is used as the exterior routing protocol. The ESnet postal system and one DNS server (NS1) are IPV6 capable. IPv6 service is provided to any site requesting IPv6 connectivity.

A Site Coordinator can request an IPv6 prefix (block of addresses) from ESnet's large IPv6 address space. The service is run as a production service and ESnet accepts and pursues trouble calls related to IPv6. ESnet manages the distributed 6TAP, participates in the 6BONE and the PAIX IPv6 exchanges, and offers to establish native IPV6 peering sessions with R&E and commercial networks as opportunities arise.
