Unclassified ARIN
Summary
BWTelcom
residential isp access us
The AS handle BWTELCOM is operated by BWTelcom.
What it's used for
- The address space carries dynamic residential connections, as evidenced by reverse DNS entries such as
74.120.61.254.dynamic.bwtelcom.netand199.255.202.254.dynamic.bwtelcom.net. - The network announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 2 observed neighbours. This high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
Notable
- The registrants for both announced IPv4 prefixes (
74.120.56.0/21and199.255.200.0/22) are listed as BWTelcom, matching the AS holder. - The inventory consists of two distinct IPv4 blocks and a single IPv6 /32, with the IPv4 space subdivided into a /21 and a /22.

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 2026-10-31, 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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
