Summary

Radiology LTD

United States of America · AI-generated

business medical static

The AS handle RADIOLOGYLTD-ASN is held by Radiology LTD.

What it's used for

  • The space carries static endpoints, as indicated by the reverse DNS entries 206-169-6-64.static.ctl.one, 206-169-6-127.static.ctl.one, and 206-169-6-190.static.ctl.one.
  • The network announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, a ratio consistent with a small, dedicated business or site-specific connection rather than a transit or large access network.
  • Traffic from this AS consists of static IP endpoints associated with the medical imaging business of Radiology LTD.

Notable

  • The registrant Radiology LTD matches the AS holder, and the netname CTL-RADIOL aligns with the operator's identity.
  • The address inventory consists of a single /24 block (206.169.6.0/24), representing a compact and self-contained 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
