About this network

Twelve addresses queried, twelve answered, and one of the twelve has a dot where the other eleven have a hyphen.

What it's used for

• A broadcasting and public warning operator's network. Four IPv4 prefixes and one IPv6 /29 announced from the Russian Federation, two thousand eight hundred and sixteen addresses, across eight observed BGP neighbours.

Notable

• Every answering name is the words for a static address, the four octets hyphenated, a label meaning user, and the operator's domain.
• One of the twelve keeps the dot between the first two octets and hyphenates the rest, so a single entry in the zone was written by hand or by a different pass of whatever generated the others.
• Three blocks share a netname built from a word for communications, the word for a network, and the operator's initials. The fourth uses a country code, a longer form of those initials and a date.
• Two blocks list only the operations centre and an abuse role, with no company object.
• The IPv6 allocation is a /29, four thousand times more addresses than the IPv4 side holds.
• Twelve addresses were queried and all twelve returned a name.

Interesting

• Full reverse coverage is rare in this range, and it makes the one malformed entry visible. Nothing checks these names against each other, so an inconsistency survives until somebody samples the zone.
• An organisation whose job includes sounding public alerts labels its addresses with the word for a user, because the same network sells connections.
