Summary

ESI Canada

Canada · AI-generated

business canada esi

The AS handle ESI-CANADA is held by ESI Canada.

What it's used for

  • The address space carries business traffic, as indicated by the consistent netname ESICA across all registered prefixes.
  • The AS announces 1024 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio that suggests a small-scale business or enterprise network rather than a large transit or access provider.

Notable

  • All RDAP registrants for the announced prefixes are listed as ESI Canada, matching the AS holder name.
  • The address inventory consists of three contiguous IPv4 blocks: 199.249.176.0/23, 199.249.175.0/24, and 199.249.178.0/24.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
