AS10070 — KRISS-AS KRISS SubDAEJONnetworks connected to backbone

AS10070 announces 2 IPv4 prefixes covering 4,096 addresses and 0 IPv6 prefixes.

About this network

KRISS-AS-KR is the Korea Research Institute of Standards and Science, the country's national metrology institute, based in the Daedeok research complex in Daejeon. Founded in 1975, it defines and maintains South Korea's measurement standards and represents the country under the Metre Convention.

What it's used for

Research and institutional connectivity for a national laboratory: calibration and standards work, physics and materials research, scientific data exchange with peer metrology institutes abroad, and the campus itself. The AS announces 2 IPv4 prefixes totalling 4,096 addresses and no IPv6 — two clean /21s, 203.254.160.0/21 and 210.98.16.0/21. Two tidy same-size blocks and nothing else is the fingerprint of a single institutional site that was allocated properly rather than accreting /24s over decades, and it is a notably larger per-site block than the Korean government agencies elsewhere in this range hold.

Notable

Carded as government: KRISS is a government-funded research institute under the National Research Council of Science and Technology, which reports to the Ministry of Science and ICT. It is a state body rather than a university, and it grants no degrees, though it hosts a graduate school in partnership with UST. The routing is consistent with an end-site: 4,096 addresses against one observed BGP neighbour, single-homed into what is almost certainly the national research network. It sells nothing; a carrier would show hundreds of adjacencies.

Interesting

KRISS keeps Korea Standard Time and broadcasts it nationally from the HLA station on 5 MHz. The handle's odd tail — SubDAEJONnetworks connected to backbone — is registry text describing the Daejeon campus links, not a separate organisation.
