AS13880 — ACSL-AS1

Network type: hosting

AS13880 announces 2 IPv4 prefixes covering 1,024 addresses and 0 IPv6 prefixes.

About this network

Two blocks from one parent range, with room for six more of the same size in the gap between them.

What it's used for

• An investment company's network. 1,024 addresses across two IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.

Notable

• The prefixes are 216.230.48.0/23 and 216.230.62.0/23, both inside the same parent range.
• The gap between them is wide enough for six more blocks of the same size.
• Both are netname ACSL-IPV4-1, initials, a protocol version and a counter.
• The AS handle is ACSL-AS1, the same initials with a different suffix and counter.
• Three upstreams serve 1,024 addresses.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Two widely separated pieces of one range mean the space between them went to other customers of whoever held the parent. Address blocks are handed out as they are asked for, so the gap is a record of other companies' requests arriving between this company's two.
• Handle and netname built from the same initials but with different suffix conventions is the common case in this range: each object was created by whoever needed it, following a scheme that existed in their head rather than in a document.
• Three upstreams for a thousand addresses is a financial firm buying availability, not capacity.
