Summary
Comwave Telecom
isp telecom hosting
Two reverse names publish what look like the hardware addresses of the modem behind them.
What it's used for
- A telecom provider's network. Sixty-five IPv4 prefixes and forty-one IPv6 prefixes announced from Canada, over a hundred and sixty thousand addresses, with fifteen observed BGP neighbours.
Notable
- Two of ten answering addresses returned names under a cable carrier's domain in the form
mta0018689aaf33-cm0018689aaf31.mta.net.cable.rogers.com, where each half is a twelve-character hexadecimal string and the two differ by two in the last digit. - The rest answer under the operator's own domain, address-derived, with a service marker that is either
tpiaordsldepending on the block. - Two blocks registered to this holder carry the netname
SHAW-CABLE, another carrier's name kept after the space changed hands. - The IPv6 announcements descend from a
/38through a ladder of lengths down to individual/48blocks, tiling one allocation. - Most registrant fields append an abuse contact with a semicolon; one block omits it.
Interesting
- Hexadecimal identifiers in reverse DNS are a real disclosure. Two pieces of customer equipment are named by what appear to be their hardware addresses, publicly, keyed to an address, and they change only when the equipment does. That makes a subscriber's kit trackable across address changes by anyone sampling the zone.
- The two service markers split the network into distinct access types, a distinction that appears nowhere in the registry and only in DNS.

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.
