AS9490 — NIS-AS Oscar Enterprise
AS9490 announces 2 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.
About this network
AS9490 (NIS-AS) is registered to Oscar Enterprise, an organisation recorded in APNIC at an address in Seocho-gu, Seoul. The name is opaque and there is no public corporate presence that plainly matches it, so this card sticks to what the routing data supports and does not guess at the business behind it.
What it's used for
The AS originates two IPv4 prefixes — 203.236.74.0/24 and 168.126.27.0/24, 512 addresses in total — and no IPv6. The visible footprint is essentially nil: RIS route collectors registered no live sessions for this AS at sampling time, so its routes are at best marginally propagated in the public table.
The second prefix is worth pausing on. 168.126.27.0/24 sits inside 168.126.0.0/16, which is KT (Korea Telecom) space — this is a sub-assignment carved out of a national carrier's block, not an independent allocation. The AS's upstreams are KT and LG DACOM, the two largest Korean incumbents. So the picture is an organisation with a handful of addresses, taking transit from both major Korean carriers, one of its two blocks numbered out of KT's own space.
Notable
- The same registrant, at the same Seoul address, also holds AS9696 under the handle EDAS-AS. Two ASNs under one opaque registrant name is worth knowing, though it proves nothing on its own — real corporate groups look the same.
- With 512 addresses, no rDNS evidence and no meaningful public identity for the holder, no confident classification of this network's purpose is supportable.
