AS10062 BHA-AS-KR Branksome Hall Asia

BHA-AS-KR is Branksome Hall Asia, an International Baccalaureate world school in Seogwipo on Jeju Island. It is the Asian campus of Branksome Hall, the Toronto independent school, and opened in 2012. AS10062 carries its campus network.

What it's used for

Everything a residential international school needs online: classroom and one-to-one learning platforms, administration, and — because a large share of pupils board on site — dormitory internet. That boarding component is the reason a school of this size runs a routed network at all rather than sitting behind a single provider connection. The AS announces 4 IPv4 prefixes totalling 1,024 addresses and no IPv6: four separate /24s from four unrelated ranges (1.249.108.0, 58.229.99.0, 58.238.84.0, 222.122.101.0), the pattern of a site that picked up a block per upstream or per phase of campus build-out.

Notable

An education network, and one of the more unusual holders in this range: a K-12 school with its own AS is rare anywhere. The routing settles the role — 1,024 addresses against two observed BGP neighbours is a single end-site multihoming to two Korean carriers and re-announcing nothing. There is no wholesale or hosting behaviour here; a carrier of any size would show hundreds of adjacencies.

Interesting

The campus sits inside the Jeju Global Education City, a South Korean government project that assembled several foreign private schools on one purpose-built site to keep Korean families from sending children abroad for schooling. That context explains the network: JGEC schools are built to international-campus standards from day one, which is why one of them holds an ASN and a Korean secondary school normally would not.
