Summary
Samsung SDS
enterprise legacy
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, and121.xranges.
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
/24networks out of ARIN space, a reminder that an AS's registry and its addresses' registries need not match.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
