Summary
TurkNet
isp transit telecom
446 neighbours, and reverse DNS that sorts every address into a product category by domain suffix.
What it's used for
- Access and transit in Turkey. 146,688 addresses in 166 IPv4 prefixes, 164 IPv6 prefixes, and 446 observed BGP neighbours.
Notable
- The oldest allocation is
TR-TURKNET-960328, dated March 1996; later ones run990212,20081126,20110112and20110513. - Twelve of eighteen sampled addresses answered, under five different suffixes:
dsl.static.turk.net,dsl.dynamic.turk.net,srv.turk.net,static.turk.netandreverse.turk.net. - All the names write the address backwards, as in
255.143.70.95.dsl.static.turk.net. - The IPv6 announcements are cut into
/45s,/46s,/47s and/48s out of2a02:ff0.
Interesting
- The suffix is the product. An address under
dsl.staticis a fixed line,dsl.dynamica pooled one,srva server range, and each of those carries different expectations for mail reputation, abuse handling and filtering. Publishing the classification in DNS lets every receiving system on the Internet apply the operator's own categories without being asked to. - 446 neighbours is one of the highest counts in this stretch of the number range. That is the profile of a network selling transit and peering aggressively at exchanges rather than one simply serving subscribers, even though it clearly does both.
- 164 IPv6 prefixes against 166 IPv4 ones is unusual and expensive. Most operators take one v6 block and announce it whole; splitting v6 as finely as v4 imports every routing-table cost of the older protocol into the newer one, on purpose.

Reputation
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
