Autonomous system
AS18661 DCA-BGP - Dunn Carney Allen Higgins & Tongue, LLP
Unclassified ARIN
Summary
Dunn Carney Allen Higgins & Tongue, LLP
legal business leased
DCA-BGP is the autonomous system handle for Dunn Carney Allen Higgins & Tongue, LLP, a legal firm.
What it's used for
- The address space is registered to Comcast Cable Communications, LLC under the netname
CCCH3-4, indicating the IP block is leased from a major cable operator rather than owned by the law firm. - The AS announces a single IPv4 prefix,
50.207.188.0/24, comprising 256 addresses, with 0 IPv6 prefixes. - With only 1 observed neighbour, the network functions as a small, isolated endpoint or site-specific connection rather than a transit or large-scale access network.
Notable
- The registrant of the announced prefix, Comcast Cable Communications, LLC, differs from the AS holder, Dunn Carney Allen Higgins & Tongue, LLP, confirming the use of third-party IP space.
- The inventory consists of a single /24 block, which is a standard size for a small business or office site allocation.

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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
