Summary

Comtech Ticaret LTD.

Turkey · AI-generated

isp residential turkey telecom

COMTECH-AS is operated by Comtech Ticaret LTD., a Turkish telecommunications provider.

What it's used for

  • The address space carries residential and dial-in access traffic, evidenced by reverse DNS entries such as Dialin255.kktc.net and Meb1.kktc.net.
  • The AS announces 9,472 IPv4 addresses across 6 prefixes with only 4 observed neighbours, a ratio characteristic of an access network serving end-users rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and dial-in connections for the Turkish market, consistent with the operator's role as a local ISP.

Notable

  • Registrants for the majority of prefixes align with the announcer, listing COMTECH ADMIN and Comtech Ticaret LTD.; the 37.218.196.0/22 block is registered under the netname CYPORTCOM.
  • The address inventory is concentrated in the 77.92.0.0/20 and 77.92.16.0/21 ranges, with smaller allocations in 37.218.196.0/22, 77.92.24.0/22, 193.201.128.0/22, and 77.92.28.0/24.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
