Summary

enterprise business infrastructure

One sixteen-bit block shredded into more than twenty announcements, every one of them filed under a two-letter netname.

What it's used for

  • A freight railway's corporate network. 66,560 addresses across 27 IPv4 prefixes plus one IPv6 prefix, 2620:196::/32, with four observed BGP neighbours.

Notable

  • Every registry record checked carries the netname CN, registered to Canadian National Railway Co.
  • Almost every prefix sits inside 165.115, announced in pieces from /19 down to /23.
  • One block, 208.67.168.0/22, falls outside that range.
  • Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

  • CN is two characters, and it is both the company's initials and the mark painted on the side of its locomotives. Netnames are usually padded with the block, the site or a ticket number; this one assumes anybody reading already knows.
  • Splitting a sixteen-bit range into more than twenty separate announcements is what a network looks like when it follows track rather than buildings. The pieces go up at different points on a line that crosses a continent, and each has to be reachable from wherever the fibre reaches it.
  • The IPv6 allocation is a single /32 against 27 IPv4 pieces. One was requested once and has never needed subdividing; the other accumulated.
  • Nothing answers a reverse lookup. A railway's network exists to move dispatch and telemetry, not to be reached from outside.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
