Unclassified RIPE
Summary
TSKB
business corporate banking
The AS handle TSKB is held by TSKB Turkiye Sinai Kalkinma Bankasi Anonim Sirketi.
What it's used for
- The address space carries corporate infrastructure, evidenced by the netname
ISNET-NETand reverse DNS entries pointing toreverse.superonline.net. - The AS announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, isolated corporate network rather than a transit or access provider.
- Traffic from this AS consists of internal corporate communications and web endpoints for the bank's operations.
Notable
- The registrant for the announced prefix is
Superonline Iletisim Hizmetleri A.S., which differs from the AS holder, suggesting the address space is leased or managed by a third-party ISP. - TSKB is a Turkish industrial development bank, and the AS serves its internal network needs.
- The inventory consists of a single /24 block, which is typical for a corporate site with limited address requirements.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
