Summary
Yonsei University
education university research legacy
YONSEI-AS-KR is the campus network of Yonsei University in Seoul, one of South
Korea's oldest and most prominent private research universities.
What it's used for
- Campus, research, and administrative networking across Yonsei's Sinchon and other campuses: labs, faculty and student services, libraries, and university-run systems.
- Roughly a /16 worth of IPv4 address space, a size typical of universities that were allocated addresses before conservation rules tightened.
Notable
- Yonsei is one of the "SKY" universities, the informal trio (with Seoul National and Korea University) at the top of Korean higher education, and its network is correspondingly large.
- Korean universities and research institutes were central to the country's early internet — Korea built one of the first TCP/IP networks outside the United States — which is why several of them hold low four-digit AS numbers.
