Summary

Isik University

Turkey · AI-generated

education university turkey

The AS handle ISIKUN is held by Isik University.

What it's used for

  • The address space carries the university's internal network, identified by the netname ISIK-NET in the RDAP registrant data.
  • The inventory consists of a single IPv4 prefix, 193.255.120.0/22, comprising 1024 addresses, with 0 IPv6 prefixes announced.
  • With only 1 observed neighbour, the network operates as an isolated endpoint for the university's campus infrastructure rather than providing transit or broad access services.

Notable

  • The RDAP registrant for the prefix 193.255.120.0/22 is listed as Abuse-C Role with netname ISIK-NET, which aligns with the registry holder Isik University.
  • The address inventory is a single contiguous /22 block, indicating a straightforward allocation for the institution's needs without complex subdivision or leasing patterns.

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 2026-11-03. 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.
