Summary

Ting Fiber

United States of America · AI-generated

residential isp fiber cable

CEDAR-NETWORKS is the AS handle for Ting Fiber, a regional internet service provider operating in the United States.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS records pointing to cedarnetworks.com and netnames such as 1CIS-NET-1, 1CIS-NET-2, and ZIPPY-NET-3.
  • The AS announces 13,312 IPv4 addresses across 22 prefixes with only 4 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • All registrants in the RDAP data are listed as Cedar Networks, which aligns with the AS holder and the reverse DNS domain.
  • Cedar Networks is the corporate entity behind the Ting Fiber brand, which provides fixed-line telecom services including internet and voice.
  • The inventory consists of three distinct netname groups (1CIS-NET-1, 1CIS-NET-2, ZIPPY-NET-3) spanning the 69.39.0.0/16, 67.223.160.0/20, and 209.140.0.0/22 ranges.

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 1,778 prefixes, as published 2026-10-20. 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.
