About this network

The AS handle ends in a hyphen with nothing after it, and half the reverse names have no domain.

What it's used for

• A regional provider. Five IPv4 prefixes and one IPv6 prefix announced from Italy, nineteen thousand addresses, across thirty-eight observed BGP neighbours.

Notable

• The handle stops mid-word, leaving a trailing hyphen where the country code should be. The holder string has the code; the handle lost it.
• Three of the six answering names are bare labels with no domain attached at all: a hyphenated pair of words, a business system with a version and a slot number, and a single mythological name.
• A fourth writes the address as ten digits run together with no separators of any kind.
• The other two follow a scheme of their own, naming the last octet and the third octet as separate words before the domain.
• Two netnames carry six-digit dates with two-digit years and a third carries a full eight-digit one, so the changeover is visible inside one holder's records.
• One block belongs to a different company under a different brand. Another block's registry lookup failed, so its details are unknown rather than absent.
• Fifteen addresses were queried and six returned a name.

Interesting

• A reverse record pointing at a name with no domain is valid and close to useless. Anything that looks it up gets a string that resolves nowhere, which is how internal host names escape.
