About this network

The holder is one company and every registry field on every block names another.

What it's used for

• A provider's network. Ten IPv4 prefixes announced from Latvia, no IPv6, four thousand and ninety-six addresses, through a single observed BGP neighbour.

Notable

• Eight of the ten netnames are built from a second company's brand, and the registrant on all ten is that company or its technical role, not the holder named in the routing record.
• Two netnames keep the holder's brand. One of them appends the first three octets of the block run together with no separators, giving an eight-digit tail.
• Two of the date-style netnames end with an extra hyphen and a digit, so the registry had to disambiguate more than one block taken the same day.
• Two of eighteen queried addresses answered, and both names are the third and fourth octets run together as six digits on the holder's domain.
• Ten prefixes and a single upstream.

Interesting

• Digits run together with no separator show up twice here, once in a netname and once in reverse DNS, which suggests both were generated by the same habit rather than the same tool.
• A holder in the routing record with another company throughout the registry is the normal shape of an acquisition that stopped halfway: routing was updated because it had to be, and the address records were not because nothing breaks if they are wrong.
