Summary
WTC Communications
cable dsl isp residential
WTC is the AS handle for WTC Communications, a Canadian cable and DSL internet service provider.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries such as
64-118-29-254.dynamic.wtccommunications.netand66-102-85-254.cable.wtccommunications.net. - The network announces 22,528 IPv4 addresses across 30 prefixes and 16 IPv6 prefixes, while maintaining only 10 observed neighbours, a ratio indicative of an access network rather than a transit provider.
Notable
- Registrants for the majority of prefixes are listed as
WTC Communications, with some blocks also listingNetwork OperationsorOperations Network; one prefix (45.62.86.0/23) is registered toNRTC Communications. - The inventory consists of multiple /21 and /22 blocks in the 45.78, 64.118, and 66.102 ranges, alongside smaller /23 and /24 allocations, reflecting a segmented internal estate for different service regions or technologies.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
