What it's used for
- The address space is primarily registered under netnames such as
STARLAN-NETandSTARLAN-208-20, indicating a corporate or business-oriented infrastructure. - Two /24 prefixes are registered to Cologix, Inc with netnames
COLOG-8andNAC-NETBLK06, suggesting leased or hosted space within a data center environment. - The AS announces 15,872 IPv4 addresses across 8 prefixes while maintaining only 1 observed neighbour, a ratio that implies a small, self-contained network rather than a transit provider.
Notable
- Registrants for the majority of the inventory align with the announcer, Starlan Telecom Corp., while the two smallest prefixes are registered to Cologix, Inc.
- The address inventory consists of a mix of /20, /21, /22, and /24 blocks, with the Cologix-registered /24s representing a distinct segment of the overall estate.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
