About this network

Three brand names live in the reverse zone, and two of them belong to companies that were renamed.

What it's used for

• A national carrier's network. One hundred and nineteen IPv4 prefixes and twenty sixth-version prefixes announced from Brazil, five hundred and thirty-eight thousand eight hundred and eighty addresses, through six hundred and fifty-nine observed BGP neighbours.

Notable

• Every netname is a bare registry record number, five or six digits, with no letters at all. Twelve blocks carry eleven different numbers, and two blocks in one parent range share theirs.
• Fourteen of eighteen queried addresses answered, spread across three domains: the current brand, a predecessor brand, and a shorter form of that predecessor with a three-letter locality inserted.
• Most names are the address with each part padded to three digits and joined by hyphens, then a word meaning fixed.
• One is a router: an interface name, a role, a hardware family, and a site code.
• One name has the reverse lookup zone for its address appended after a complete domain.

Interesting

• Numeric netnames come from a registry that identifies a block by its own record rather than by any label the holder chose. The result is a record where nothing but the registrant says who this is.
• Six hundred and fifty-nine neighbours on half a million addresses is a carrier that sells transit as much as access, and the predecessor brands still answering are the acquisitions that built it.
