SIPB IPv6 current status

Our site name in the 6bone registry is MIT-SIPB.

Hardware and software

Our main router, limekiller.mit.edu, is a Sun SPARCstation 5 running a recent vintage of NetBSD-current, which has integrated a version of the KAME IPv6 stack. We're using the Zebra BGP4+ implementation to announce our network blocks to our external connections, and are using static routes internally for now.

Outside connections

Our connection is via several IPv6-over-IPv4 tunnels from limekiller.mit.edu to several different 6bone backbone sites:

We are currently using an address block allocated from MERIT: 3ffe:1ce1::/32. We may renumber at any time; this is the way of IPv6.

We also provide tunnels to other folks, mostly in the general New England area. If you're interested in a tunnel, send mail to <sommerfeld@alum.mit.edu>

MIT campus IPv6

One of the goals of the project is to let folks on the MIT campus develop some experience with IPv6 protocols. To do this, there's a plan allowing IPv6 addresses to be assigned to machines at MIT which want them.

Active subnets

We provide native IPv6 service on two subnets in W20: SIPB-ETHER (18.181/16) and W20-ETHER (18.187/16) through two ethernet interfaces on limekiller; both statically configured addresses and stateless address autoconfiguration are enabled.

There's also service on E40-STAFF-ETHER (18.177/16), tunnelled via mumps-11.mit.edu, and service to the AI lab, tunneled via repo-man.ai.mit.edu

If you want IPv6 service enabled on subnets other than the ones listed here, and have a machine capable of serving as a tunnel endpoint for the subnet, send mail to <sommerfeld@alum.mit.edu>

IPv6 addresses on MITNET subnets are assigned based on a fairly simple addressing plan .
