AS9852 SAMIL-AS Samil PwC

AS9852 (SAMIL-AS) is held by Samil PwC (Samil PricewaterhouseCoopers), the Korean member firm of the PwC network and the largest accounting firm in South Korea. It provides audit, tax, deals and consulting services. This is a professional-services firm's own corporate AS, not a provider network of any kind.

What it's used for

The routing evidence is a small, multihomed enterprise edge. RIS sees four IPv4 prefixes totalling roughly 1,792 addresses: a 210.108.80.0/22 with a 210.108.84.0/24 alongside it, plus 211.51.39.0/24 and 210.120.73.0/24 from unrelated Korean ranges. There is no IPv6, and three BGP neighbours are observed.

Three upstreams against under 2,000 addresses is the classic corporate posture: the firm is buying resilience, not reach. A network selling transit or hosting at this address count would show orders of magnitude more neighbours. The space is best understood as the firm's public-facing perimeter, its client-facing portals and secure file exchange, and the externally reachable side of its internal estate. For an audit firm handling client financial data, holding its own address blocks also means counterparty allowlists and VPN endpoints survive a change of carrier, which is a good reason for a non-technology business to run an AS at all.

Notable

• Card the specific network: this is the Korean member firm's own AS, distinct from PwC's global or other member-firm networks.
• The mixed prefix origins (one contiguous /22+/24 plus two isolated /24s) suggest assignments accumulated from more than one Korean upstream.
