AS15182 — ALE-NAR-CALI-RD-01

AS15182 announces 3 IPv4 prefixes covering 1,792 addresses and 0 IPv6 prefixes.

About this network

Three routes for one contiguous run, because the run starts one block above a boundary.

What it's used for

• A communications equipment vendor's network. Three IPv4 prefixes announced from the United States, no IPv6, and two observed BGP neighbours.

Notable

• The three blocks are contiguous: 198.206.181.0/24, 198.206.182.0/23 and 198.206.184.0/22 sit end to end with no gap between them.
• They cannot be announced as fewer routes, because the run begins one block above the alignment a single covering prefix would need. Three is the minimum here, not a mistake.
• All three carry the same netname, prefixed with a type word rather than named for anything, and the same registrant.
• The AS handle is a four-part string: the company initials, a region code, a site code and a counter.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• This is the counter-example to a pattern that shows up constantly in this range. Adjacent blocks announced separately usually means nobody aggregated them. Here the split is forced by arithmetic, and the three sizes are exactly what a minimal covering set looks like for a run of seven blocks starting at an odd offset.
• A four-part handle encodes a location and a role in a field with no schema. It reads as structured data, but nothing validates it, and the expansion of each part exists only in the head of whoever registered it.
• Seventeen hundred addresses behind two upstreams is a corporate network, not a product one.
