AS15843 Galatasaray Universitesi
Unclassified APNIC
Summary
Galatasaray Universitesi
education research business
The handle is the university's name and nothing else, and the block lists no institution at all.
What it's used for
- A university's network. One IPv4
/22announced from Turkey, no IPv6, one thousand and twenty-four addresses, across two observed BGP neighbours.
Notable
- The AS handle is the institution's name written in full with a space, with no hyphen, no country code and no suffix for an autonomous system, which almost nothing else in this range does.
- The only registrant on the block is a role named after the registry's abuse field, so the university itself has no object on its own addresses.
- The netname is the institution's three initials and the three letters for a network.
- One thousand addresses are announced as a single route.
- The routing archive has carried this number since the earliest data it holds.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Handles are supposed to be terse identifiers, which is why nearly every one here is capitals and hyphens. A handle written out as ordinary words is what you get when the form is filled in by somebody answering the question rather than following the convention, and it has stood for twenty-five years.
- A thousand addresses is a small campus allocation, from a time when a university took what it needed rather than what it could get.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-02, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
