AS16283 LODMAN-AS2 Metropolitan Area Network LODMAN

The handle spells out what the acronym means and then repeats the acronym anyway.

What it's used for

• A metropolitan academic network. Seven prefixes announced from Poland, one of them IPv6, twenty-six thousand six hundred and twenty-four addresses, through four observed BGP neighbours.

Notable

• The AS handle is the network's name, a numeral, then the three words the name abbreviates, then the name again. One field states the same thing three ways.
• All six IPv4 blocks share two netnames, each a country code, the network's name, and a six-digit date with the century dropped. The two dates are six weeks apart.
• Every block is registered to the university and to an abuse role named after the network rather than the institution, so the operator and the owner are recorded separately.
• Two of eighteen queried addresses answered, both on a departmental subdomain under the city's name. One is a three-letter label with a numeral, the other a three-letter label with a two-digit number.
• Twenty-six thousand addresses behind four upstreams, with almost nothing published in reverse DNS.

Interesting

• Academic metropolitan networks were built to connect a city's universities to each other, then became the uplink for all of them. The abbreviation names the city network; the registrant names whichever institution agreed to hold the paperwork.
• Two dates six weeks apart, both from the same era, are the trace of an allocation that arrived in two pieces because the first request was granted smaller than asked.
