Summary
DACS-IX
transit business us
DACSIX-CENTRAL is operated by DACS-IX.
What it's used for
- The address space is registered to Cogent Communications, LLC with the netname
COGENT-A, indicating the IP inventory is leased or inherited from Cogent. - The AS announces 256 IPv4 addresses and 4 IPv6 prefixes while maintaining only 3 observed neighbours, a ratio that suggests a transit or interconnection role rather than a large access network.
Notable
- The registrant
Cogent Communications, LLCdiffers from the AS holderDACS-IX, reflecting the use of Cogent-owned address space by a separate network operator. - The inventory consists of a single IPv4 prefix,
38.103.121.0/24, and four IPv6 prefixes within the2602:fb5b::/48range.

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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
