Summary
Sabancı University
education research business
A university on 8,192 addresses reached through exactly one neighbour.
What it's used for
- The campus network of a private Turkish university. 8,192 addresses in a single IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.
Notable
- The whole inventory is
159.20.64.0/19, netnameTR-SABANCIUNIVEDU-20110909. - The registry lists the university itself alongside a generic abuse role.
- First observed in the routing archive in August 2000.
- Three addresses were sampled and none returned a name.
Interesting
- Universities almost always reach the internet through a national research and education network rather than through commercial providers, and one neighbour is what that looks like from outside. The single upstream is a shared academic backbone, and everything the campus reaches goes through it.
- The netname carries a 2011 date while the AS has been announcing since 2000. The record was rewritten at some point, most likely when the block moved between registry objects or the university took direct responsibility for it. Dates in netnames record paperwork events, not the age of the network.
- A /19 for one campus is generous by current standards and unremarkable for its era. Universities were among the earliest requesters of address space and received allocations sized for a future where every device had a public address, which is why campus networks still have room that newer organisations of the same size cannot obtain.
- No IPv6 announced, from an institution whose research departments are the usual place to find it deployed first.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
