About this network

Blocks numbered one and three, with nothing filed as two.

What it's used for

• A provider's network in Canada. 1,536 addresses across two IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.

Notable

• 158.51.216.0/22 carries the netname ALDERA-NL-01 and 199.241.44.0/23 carries ALDERA-NL-03.
• Both are registered to the company, and both netnames carry the same two-letter region code as the AS handle.
• Six addresses were queried for reverse DNS and none returned a name.
• The AS first appeared in routing on 2000-08-18.

Interesting

• The gap in the numbering is the interesting part. A second block was filed at some point and is no longer here, either returned to the registry, sold, or moved under another AS. Sequence numbers in netnames are one of the few places where a network's history leaves a mark that survives the thing it counted.
• The region code in both the handle and the netnames means the operator plans by province and expects to hold space in more than one. Numbering by region rather than by purpose is the convention of a company that grows geographically.
• Two blocks from unrelated ranges, one recent and one much older, is address space acquired at two different moments in the market.
• Two upstreams and nothing published in reverse DNS is the ordinary shape for a small provider whose subscribers publish nothing themselves.
