AS8278 TUC-AS

TUC-AS belongs to the Technical University of Crete (Polytechneio Kritis) in

Chania. It announces the university's classic academic 147.27.0.0/16 plus an

IPv6 /48, connected to the Greek research network.

What it's used for

• Campus networking for a Greek engineering university: departments, labs, student residences, and public-facing university services.
• Reverse DNS reads like a departmental map, with per-school subdomains under tuc.gr — dsslweb.dssl.tuc.gr, melenia.logistics.tuc.gr, zeus.hydromech.tuc.gr, athena.ermes.tuc.gr. Named machines per lab, in the old university style, rather than numbered pools.
• Student housing appears in the same space (estia04.estia.tuc.gr; estia is the hall of residence).

Notable

• Institutional address space. Traffic from this /16 is staff, students and research systems. There is no commercial hosting and no subscriber broadband here, so it should never be read as an eyeball or hosting network even though student-residence addresses behave a little like home users.
• A full /16 for a single mid-sized university is characteristic of the era when the space was assigned: academic institutions received generous blocks that today look far larger than their machine count.
