AS10160 KDDIKOREA-AS-KR KDDI KOREA

KDDIKOREA-AS-KR is the network of KDDI Korea, the Seoul subsidiary the Japanese

carrier KDDI set up in 1999 to sell telephony, corporate internet access and data

centre services inside South Korea.

What it's used for

• Enterprise connectivity and colocation for corporate customers in Korea, many of them Japanese multinationals that want the same supplier on both sides of the strait. KDDI Korea has run an Internet Data Center since 2000, moved to Seoul's Mapo district in 2016.

Notable

This is a business network — a corporate-facing service provider — rather

than an eyeball ISP or a wholesale carrier, and the neighbour count is what rules

those out. The pack records two observed BGP neighbours against 65 announced

IPv4 prefixes and 24,576 addresses. A network that peers with only two other

ASes is buying transit at both ends and selling connectivity onward to

customers, not to networks: real carriers of this address size sit on

hundreds of adjacencies.

The prefix list is the other half of the story. One aggregate (119.59.32.0/19)

plus roughly sixty individual /24s in 61.106, 211.111 and 61.251 is exactly

how a provider carves space when each customer or each rack tenant gets its own

/24. Those blocks are self-registered to the holder, so this is a real operator

whose space happens to be finely sliced, not an address-broker pattern.

Interesting

• KDDI's global data-centre estate trades under the Telehouse brand; the Korean IDC is the local expression of the same standard.
