Unclassified ARIN
Summary
Comcast Cable Communications Management
telecom enterprise business
A cable giant's second network, small enough to fit in two blocks.
What it's used for
- Internal network space for a large cable operator, held under a separate management entity. 1,536 addresses across two IPv4 prefixes, with four observed BGP neighbours and no IPv6 announced.
Notable
208.79.64.0/22and199.27.170.0/23both carry the netnameCOMCAST-COMM-MGT, matching the AS handle exactly.- Both blocks are registered to the management company rather than to the operating one.
- Six addresses were queried for reverse DNS and none returned a name.
- The AS first appeared in routing on
2000-08-18.
Interesting
- Very large carriers run more than one AS, and the extras are rarely the interesting part of the business. This one holds a small amount of space under the legal entity that manages the group rather than the one that sells service, which is the usual home for corporate systems, acquired networks and anything that needs to be kept out of the consumer routing plan.
- Four upstreams for such a small footprint is more redundancy than the address count suggests, and points at something that must stay reachable regardless of which part of the parent network is having a bad day.
- The netname repeating the AS handle with nothing added is the mark of records created in one sitting by someone with a naming rule rather than a description to give.
- Nothing published in reverse DNS keeps the internal estate invisible to anyone mapping it from outside.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
