AS16186 — ASN-SSC

AS16186 announces 10 IPv4 prefixes covering 15,872 addresses and 5 IPv6 prefixes.

About this network

The reverse names are short strings of letters and digits that share a prefix within each block and say nothing about the address.

What it's used for

• A hosting and access provider. Ten IPv4 prefixes and five IPv6 prefixes announced from Norway, fifteen thousand eight hundred and seventy-two addresses, across seventeen observed BGP neighbours.

Notable

• Nine of eighteen queried addresses answered. Eight give a compact string of five to seven characters mixing letters and digits, then two letters for an address and the company domain.
• Within each block those strings share their first four or five characters and differ at the end, so the scheme encodes the block and then the address, in a form no reader can decode by eye.
• The ninth answer breaks the pattern completely: two letters for a gateway on an unrelated national domain.
• Nine netnames share a country code, a third brand that appears nowhere else in the record, and a date, with dates running from the first weeks of two thousand and one to two thousand and twenty.
• A tenth block is named for a hosting product and lists only an abuse role.
• The AS handle is three letters matching the reverse domain rather than the holder's name.

Interesting

• Encoded hostnames are compact and stable, and they leak nothing. Whether that is a feature or an accident of the generator, the effect is the same: the name identifies the address without describing it.
