Summary

Turkcell

Turkey · AI-generated

mobile telecom isp

One point seven million addresses, thirty IPv6 blocks, and most of them registered to an abuse desk rather than to the company.

What it's used for

  • A mobile operator. One hundred and eleven IPv4 prefixes and thirty IPv6 prefixes announced from Turkey, more than one million six hundred thousand addresses, through one observed BGP neighbour.

Notable

  • Most netnames are a country code, the brand and the word for the internet, with no date, and the only registrant listed on them is the operator's abuse handling role. The company itself appears on just two blocks, which use a dated netname template instead.
  • The IPv6 allocations are cut at unusual boundaries, several of them at sizes that sit between the round numbers most operators use, which is the mark of a very large space subdivided by region or service.
  • The IPv4 blocks run from large aggregates down to small ones across more than a hundred entries, mostly in a handful of contiguous ranges.
  • Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

  • Mobile networks hold enormous address space for a subscriber base that is almost never reachable from outside. Handsets get addresses to make connections, not to receive them, and a single such operator can hold more numbers than a small country's fixed-line providers combined.
  • Naming an abuse role as the registrant of record on most blocks is a practical choice for an operator whose ranges generate complaints continuously: whoever writes in reaches the desk that can act.

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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
