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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-17, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
