Summary
CTI Fiber
cable dsl isp regional
The AS handle CTIFIBER is operated by CTI Fiber.
What it's used for
- The address space carries residential and business access traffic, evidenced by reverse DNS entries pointing to
ctifiber.comandctitech.comdomains. - The network announces 10,240 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining only 7 observed neighbours, a ratio indicative of a regional access provider rather than a transit carrier.
Notable
- All registrants for the announced prefixes are listed as CTI Fiber, matching the AS holder name in the registry.
- The operator is also known as Computer Techniques, a regional cable and DSL provider serving the United States.
- The inventory consists of three distinct IPv4 blocks: 72.9.112.0/20, 160.32.224.0/20, and 66.11.232.0/21, alongside a single /32 IPv6 allocation.

Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,771 prefixes, as published 2026-10-15. 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.
