Autonomous system
AS16731 AS16731 - Royal Bank of Canada
Unclassified ARIN
Summary
Royal Bank of Canada
finance enterprise business
Three blocks, two netname counters, and the number between them is missing.
What it's used for
- A bank's network. Three IPv4 prefixes announced from Canada, no sixth-version space, one thousand and twenty-four addresses, through four observed BGP neighbours.
Notable
- The AS handle is the two letters for an autonomous system, the number, a dash, and the holder's full four-word name.
- All three blocks are registered to that same name, under two netnames built the same way: the bank's three initials, the word for a network, and a two-digit counter.
- Two blocks in one parent range share the higher counter; the third, in a different range, carries a counter two lower.
- The value between the two is absent here, which means it was assigned to a block this autonomous system does not announce.
- Nine addresses were queried for reverse DNS and none returned a name.
Interesting
- Netname counters are handed out per organisation, and routing is arranged per purpose. The two have nothing to do with each other, so a gap in the sequence is the normal case rather than a fault: the missing network exists, it is simply announced from somewhere else in the estate.
- Reading three consecutive counters as one system is the trap. The registry numbers what an organisation was given; the routing table shows how it chose to split that up afterwards.
- Four upstreams on a thousand addresses is redundancy sized for the consequence of being unreachable, not for the volume of traffic.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, 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: 447 networks and 1,852 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.
