About this network

The network of Samsung SDS, the IT services and data centre arm of the Samsung group, registered with APNIC under the handle SAMSUNGSDS-AS-KR. Samsung SDS runs the group's corporate IT, cloud, and data centre infrastructure.

What it's used for

• Corporate networking and data centre capacity for Samsung affiliates in South Korea. Reverse DNS across its space resolves into samsung.co.kr, including host names that look like internal user and compute systems.
• The AS announces a large IPv4 footprint, over a million addresses, drawn mostly from Korean 203.x, 210.x, 211.x, and 121.x ranges.

Notable

• This is enterprise space that happens to be very large. The size reflects the scale of the Samsung group's internal estate, not a consumer subscriber base, so addresses here belong to a company's staff, offices, and machines.
• Samsung SDS is a distinct business from Samsung Electronics' consumer products. It sells IT outsourcing, cloud, and logistics platforms, largely to other Samsung affiliates.

Interesting

• Although the network is Korean and managed under APNIC, the AS also announces a couple of /24 networks out of ARIN space, a reminder that an AS's registry and its addresses' registries need not match.
