Summary
CTDI
business engineering logistics telecom
The AS handle CTDI-WC is held by CTDI.
What it's used for
- The address space carries corporate infrastructure for an engineering and logistics firm, evidenced by the netname
COMMUNICATIONS-TEST-DESIGNand registrantCTDIon the announced IPv4 blocks. - The AS announces 512 IPv4 addresses across 2 prefixes and 37 IPv6 prefixes, while maintaining 16 observed neighbours; this ratio of modest address inventory to a moderate number of peers suggests a business network with specific connectivity requirements rather than a large-scale transit or residential provider.
Notable
- The RDAP registrants for both announced IPv4 prefixes (
192.94.45.0/24and192.94.46.0/24) areCTDI, which aligns with the AS holder name. - CTDI is a global leader in engineering and logistics, providing technical supply chain solutions to telecom carriers, cable companies, and OEMs.
- The IPv6 inventory consists of multiple /48 and /47 prefixes under the
2620:131:1000::/46range, indicating a structured internal allocation for the company's distributed operations.

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: 442 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.
