Summary

United States of America · AI-generated

business managed-services denver

FULLDUPLEX-DEN is operated by Full Duplex Inc.

What it's used for

  • The address space carries managed IT and cloud application services, with netnames including FULLDUPLEX-DENVER, FULLD, and FD-WEST-NE registered to Full Duplex Inc.
  • The AS announces 6144 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, with 6 observed neighbours, indicating a business network providing managed infrastructure rather than mass residential access.
  • Traffic from this AS consists of managed cloud endpoints and application hosting for enterprise clients, reflecting the company's focus on tailored IT services and professional infrastructure management.

Notable

  • Registrants for the majority of prefixes align with the announcer, listing Full Duplex Inc for FULLDUPLEX-DENVER, FULLD, and FD-WEST-NE, while COGENT-A and CCCH3-4 indicate leased or historical space from Cogent Communications and Comcast Cable Communications.
  • The address inventory is a mix of /21, /22, /23, and /24 blocks, with some prefixes registered to third parties like Cogent and Comcast, suggesting a combination of owned and leased infrastructure.

Reputation

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.
