What IP addresses might you see at MIT ?
|This article collects information from multiple sources and presents it on a single page as a convenience, but could be out of date or missing information.|
The ranges in the following table were compiled from a variety of locations, including ARIN data and an MIT Libraries page.
|Range||CIDR Notation||ARIN Info||Organizational Entity|
|184.108.40.206 - 220.127.116.11|| 18.104.22.168/9
||MIT-2||Most of campus|
|22.214.171.124 - 126.96.36.199||188.8.131.52/15||MIT-2||CSAIL at Stata Center, on campus|
|128.52.*.*||184.108.40.206/16||MIT-2||Artificial Intelligence Lab, on campus (largely unused as of 2012)|
|129.55.*.*||220.127.116.11/16||MIT||Lincoln Laboratory, Lexington, MA|
|18.104.22.168 - 22.214.171.124||See note 2 below||MIT-7||Haystack Observatory, Tyngsboro, MA|
|126.96.36.199 - 188.8.131.52||184.108.40.206/22||MITNS||ESnet* range used by LNS (Lab for Nuclear Science).|
|220.127.116.11 - 18.104.22.168||22.214.171.124/20||PSFC-1||ESnet* range used by Plasma Science Fusion Center, on campus|
*ESnet (Energy Sciences Network) is used by universities, research labs, national labs, etc.
Note 1: There are two separate ranges: 126.96.36.199/16 and 188.8.131.52/16.
Note 2: Haystack's IP range is actually 6 consecutive /24s. That is, 184.108.40.206/24, 220.127.116.11/24, 18.104.22.168/24, etc.
Woods Hole Oceanographic Institution ("WHOI") has a long affiliation with MIT, and in some cases, their machines count as "on campus" (e.g. for access to outgoing-legacy.mit.edu), whereas in other cases they don't (access to some MIT Libraries digital resources). Users at Woods Hole who are unable to access certain digital resources on campus should try using the VPN client or contacting the administrators of that resource.
Woods Hole has the IP address range 128.128.*.* (a/k/a 22.214.171.124/16, http://whois.arin.net/rest/net/NET-128-128-0-0-1)
The MIT GUEST wireless network is designed for use by visitors, alumni/ae and other people without formal MIT affiliation. Devices using the MIT GUEST wireless network are tunneled through an addresses translation gateway, with external addresses in the range 126.96.36.199/24 (188.8.131.52 - 184.108.40.206). The MIT GUEST wireless network also blocks many ports.
This does NOT count as "on campus" for the most part. MIT Community members using MIT GUEST who need to use MIT resources should connect to MIT SECURE wireless
