About this network

The same reverse-name scheme written two different widths depending on which range the address is in.

What it's used for

• A provider's network, now held by a national carrier. Six IPv4 prefixes announced from the Russian Federation, no IPv6, eight thousand one hundred and ninety-two addresses, across two observed BGP neighbours.

Notable

• Eight of eighteen queried addresses answered. Five use a letter, the third octet, another letter and the last octet. Three use the same two letters but put all three leading octets, hyphenated, in the first slot.
• One of the eight inserts an extra label for static addresses between the host part and the domain, so three variants of one scheme are live at once.
• The netnames split three ways: a country code with the carrier's initials and a date, a country code with the brand in capitals, and a country code with the brand in mixed case.
• The AS handle carries the carrier's name with a full stop in the middle, then the words for a technical team.
• Five of the six prefixes are nested inside each other's space.

Interesting

• The two widths exist because the scheme was designed for one range, where the leading octets were constant and could be dropped, and then reused on a second range where they could not. The letters stayed; the amount of address they carry did not.
• A brand surviving in every reverse name while the routing record names its acquirer is the usual order of events. DNS is the last thing to be renamed because renaming it breaks things.
