About this network

One block is registered to a privacy placeholder, under a netname that names the company anyway.

What it's used for

• A toy manufacturer's network. Five IPv4 prefixes announced from the United States, no sixth-version space, two thousand and forty-eight addresses, through seven observed BGP neighbours.

Notable

• The AS handle is the company name alone, with nothing added for the number or the protocol.
• Two blocks are named for the company, the two letters for a data centre, and a three-letter site code, one code per block.
• One of those two is registered not to the company but to a generic privacy placeholder, while its netname still spells the company out in full.
• The other three share a single netname: a short form of the company name, the three letters for a network, and a zero-padded counter.
• Their registrant carries a department after a semicolon rather than a person.
• Fifteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A privacy placeholder hides the registrant field and nothing else. The netname beside it, the four sibling blocks in the same parent range, and the handle on the autonomous system all say the same name. Redaction only works if every field is redacted together.
• Two site codes on two data centre blocks are a pair of buildings, and the counter on the other three never advances past one. The estate was named once and then simply grew.
