About this network

Every reverse name is the address written backwards, on a domain naming the regional branch rather than the institute.

What it's used for

• A research institute's network. Four IPv4 prefixes announced from the Russian Federation, no IPv6, three thousand and seventy-two addresses, across two observed BGP neighbours.

Notable

• Five of twelve queried addresses answered, and all five are the four octets in reverse order followed by a three-letter domain.
• That domain is a contraction of the regional branch of the national academy, not of the institute named as holder, and it appears again as one block's netname with a country code.
• The other netnames are a country code, the institute's initials, and a date, with two blocks sharing the date 20160629.
• The registrant text differs between blocks by one word: some name the branch of the academy, others the branch and the academy joined without it.
• The routing archive first saw this number in the middle of the first decade, later than most of its neighbours.

Interesting

• Reversed octets in a reverse name are not redundant, even though the lookup already knows the address. They make the answer self-describing, so a log line carrying only the name still tells you which address it came from.
• A branch domain shared across institutes is how academy networks were built: one regional operator ran the addresses and the DNS, and the individual institutes appear only in the paperwork.
