Summary

Seri Bilgi Teknolojileri

Turkey · AI-generated

business it-services turkey

The AS handle SERI is held by Seri Bilgi Teknolojileri Destek Hizmetleri ve Ticaret Limited Sirketi.

What it's used for

  • The address space carries corporate IT infrastructure, with netnames KYN-GTS-129-35 (Kyndryl) and TR-ISNET-20021230 (ISNET ROLE).
  • The inventory consists of 512 IPv4 addresses across 2 prefixes, with only 1 observed neighbour, indicating a small, isolated business network rather than a transit or access provider.
  • Traffic from this AS represents internal corporate operations and IT support services for the holder organisation.

Notable

  • Registrants differ from the announcer, listing Kyndryl and ISNET ROLE for the respective prefixes, suggesting leased or historically allocated space.
  • The address inventory is minimal, comprising two /24 blocks in Turkey.

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: 453 networks and 1,848 prefixes, as published 2026-11-13. 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.
