AS8748 Blekinge Tekniska Hogskola

Blekinge Tekniska Högskola (Blekinge Tekniska Hogskola) — the Blekinge

Institute of Technology, a Swedish public university in Karlskrona and

Karlshamn focused on engineering, IT and software.

What it's used for

• Campus networking for the university: staff and student subnets, servers and eduroam wireless. rDNS across the space lands on bth.se — gateways such as bth-gw.net.bth.se, service hosts like redirect.bth.se, and wireless clients under host-IP-ADDR.eduroam.bth.se.
• Two prefixes only, roughly 10,000 addresses, announced through a single upstream. That is the standard shape of a Swedish university connected to SUNET, the national research and education network.

Notable

• This is institutional address space, not consumer or hosting space. Addresses geolocate to a campus, and the population behind them is students, researchers and staff. There are no dynamic, PPPoE or subscriber-pool naming conventions anywhere in the sampled rDNS.
• The eduroam naming is the giveaway of an academic network: eduroam is the global federated Wi-Fi roaming service used by universities, so a visiting researcher's traffic can appear from this AS.

Interesting

• BTH is one of Sweden's smaller universities but has an unusually strong software-engineering and telecoms profile, a legacy of Karlskrona's role as a naval and telecom-industry town.
