Summary

NetAccess Systems

Canada · AI-generated

isp residential cable dsl

The AS handle NETACCESS-SYSTEMS is held by NetAccess Systems Inc.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries like ip255.216.145.107.nas.net and netnames such as NAS-1 and NAS-2.
  • With 7424 IPv4 addresses announced across 16 prefixes and only 10 observed neighbours, the high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants are predominantly NetAccess Systems Inc, though specific blocks are registered to the Canadian Centre for Occupational Health and Safety (CCOHS), Affinity Associates Consulting Inc. (AFFINITY), and eidos information spaces corp. (EIDOS-CA).
  • The inventory consists of a mix of larger /21 and /22 blocks alongside numerous /24 prefixes, all located in Canada.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
