AS16597 — SPC

AS16597 announces 2 IPv4 prefixes covering 8,192 addresses and 0 IPv6 prefixes.

About this network

Both contacts are departments spelled out in full, and both blocks are numbered by hand.

What it's used for

• A college's network. Two IPv4 prefixes announced from the United States, no IPv6, eight thousand one hundred and ninety-two addresses, through one observed BGP neighbour.

Notable

• The two netnames are the college's initials, three letters abbreviating the word block, and a counter: one and two.
• The blocks are the same size and sit on unrelated ranges, so the counter records the order they were acquired in and nothing else.
• Both list the same two extra contacts, each a department written out at full length: an operations centre and a group named for the act of reporting abuse.
• The AS handle is the college's three initials alone, with nothing appended.
• Six addresses were queried for reverse DNS and none returned a name.
• The country field is missing the small word between the two halves of the country's name.

Interesting

• A contact named for reporting rather than for handling is a careful piece of wording. It describes what the address is for, not what will happen next, which is more honest than most abuse contacts manage.
• Two equal blocks numbered in order is the clearest netname scheme in this range: it says how many there are, which came first, and nothing anybody has to decode.
• Eight thousand addresses on one upstream is a campus that treats its connection as a single service. The blocks are doubled; the path out is not.
