About this network

The handle explains, in a sentence, that this number carries the non-educational half of the network.

What it's used for

• An academic computing centre's commercial network. Eleven IPv4 prefixes and one IPv6 /36 announced from Poland, twenty-two thousand and sixteen addresses, across four observed BGP neighbours.

Notable

• The AS handle is two hyphenated codes, then a clause saying which part of the network this is, then a city and a country with no space after the comma.
• Ten netnames are a country code, the network's name and a date, and those dates come in two forms: six digits for the older allocations and eight for the newer.
• The eleventh joins the network's name, the centre's four initials, the word for a network, a three-letter suffix and the block's own third octet.
• The one answering name is a gateway label, the word for a static address, that same three-letter suffix and a number, on the centre's domain.
• Contacts include an operations role and one whose name ends in the words for officers who respond to abuse.
• Of eighteen addresses queried, one returned a name.

Interesting

• Academic networks are usually barred from carrying commercial traffic, so centres run a second autonomous system for the customers they are allowed to serve. The handle spells this out because the distinction is a licence condition, not a technical one.
• The three-letter suffix in the netname and in the reverse name is the same marker for the commercial side, carried through two unrelated systems.
