AS12402 — UOPIRAEUS

AS12402 announces 4 IPv4 prefixes covering 4,608 addresses and 1 IPv6 prefixes.

About this network

The campus network of a Greek university, reached through the national research network.

What it's used for

• Campus and departmental connectivity. 4,608 addresses in four IPv4 prefixes, one IPv6 /48, a single observed BGP neighbour.

Notable

• All four prefixes share the netname UOPIRAEUS-NET and are registered to the University of Piraeus NOC — the operators, named as the responsible party rather than the institution.
• The IPv6 announcement is 2001:648:24a0::/48, a /48 carved out of 2001:648::/32. The IPv4 blocks come from two separate ranges, 195.251 and 83.212.
• One neighbour. A campus network reaches the internet through the research network and nothing else.

Interesting

• Reverse DNS is organised by department, not by building or by subnet. noc.unipi.gr holds subnetCSVM and subnetTECH; ted.unipi.gr holds xifi122 and lab30760; naf.unipi.gr holds mstam3. Machines named for a project, a lab inventory number and somebody's initials, filed under the department that bought them.
• The subnet-prefixed names are a network team's own convention: an address named after the subnet it anchors, so that a traceroute reads as a map. Universities produce more legible reverse DNS than most commercial networks because the people naming the machines are the people using them.
