Summary

Bell Canada

Canada · AI-generated

residential isp canada legacy

The AS handle ONTL-2002 is held by Bell Canada.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as pucdsl-804.puc.net and onlinkI-gw.onlink.net, alongside legacy ontera.net and fdm4.com hostnames.
  • With 22,784 IPv4 addresses announced across 9 prefixes and only 1 observed neighbour, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • All RDAP registrants for the announced prefixes are listed as Bell Canada, with netnames consistently prefixed NTL-ONLINK, aligning the registry data with the current operator.
  • The address inventory is composed of a mix of larger /19 and /20 blocks and smaller /23 and /24 blocks, reflecting a legacy allocation structure that has been maintained since the AS was first seen in 2002.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
