Summary
TELUS Communications
isp legacy
TELUS-7861 belongs to TELUS Communications Inc., the Vancouver-headquartered Canadian carrier. It is a secondary TELUS autonomous system, not the company's main network: TELUS's principal AS is AS852, which is also AS7861's only upstream.
What it's used for
- Announcing about 35 fragmented legacy ARIN blocks out of TELUS's older Canadian allocations — pieces of
204.191.0.0/16,207.34.0.0/16,209.91.0.0/16,209.29.0.0/16,209.121.0.0/16and154.11.0.0/16. All are registered to TELUS itself; there are no downstream networks. - The reverse DNS is a mix rather than a single population, which is why this AS resists a clean classification:
- Legacy dial-up pools still exist, e.g.
ip4-25.eyrkonaeac10.dialup.ca.telus.com. - Business and hosted customers reverse to their own domains, and some space belongs to TELUS's own labs (
mail.sfbdemo.teluslabs.net). - Whole /24s answer with wildcard-generated placeholder names of the form
host44.158.115.209.in-addr.arpa, which carry no information at all.
Notable
- Do not read TELUS's consumer broadband business onto this AS. TELUS's residential eyeball traffic lives on AS852. AS7861 is a grab-bag of older assignments, and with dial-up remnants, business customers and lab space all in the same footprint there is no honest single kind for it.
- The blocks are Canadian and TELUS-registered, so geolocating them to Canada is safe even though classifying them is not.
Interesting
- The technical contact on every one of these blocks is still the ARIN handle
PSINET-CA-ARIN, now attached to TELUS's IP Address Administration. TELUS bought PSINet's bankrupt Canadian operation in June 2001, and AS7861 was registered in January 2002 — the handle is a fossil of that deal.

Reputation
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 1,768 prefixes, as published 2026-10-12. 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.
