AS10174 MBC-AS-KR Munhwa Broadcasting Corporation

MBC-AS-KR belongs to Munhwa Broadcasting Corporation, one of South Korea's

three national terrestrial television and radio broadcasters. This is the

corporate network of a media company, not a consumer ISP.

What it's used for

• Carrying MBC's own production, newsroom, playout and public-facing web infrastructure, plus the links between its Seoul headquarters and the regional MBC stations that make up the national network.

Notable

• The kind here is business (an enterprise media network), and the routing says so plainly. RIS sees 7 IPv4 prefixes, 9,728 addresses and just 2 observed neighbours. Two neighbours is the signature of a customer network buying transit from a pair of upstreams for redundancy. A broadcaster with MBC's audience would need thousands of neighbours if it were carrying viewers; instead it carries staff and systems, and reaches its audience over the airwaves and over other people's networks.
• The address footprint fits that reading. It is dominated by one legacy 203.238.224.0/19 from KRNIC's early allocations, with a few later APNIC /24s (103.3.36.0/24–103.3.39.0/24, 103.164.78.0/24–103.164.79.0/24) bolted on. That is an organisation that got a large block decades ago and has since only topped up.

Interesting

• No IPv6 is announced at all, which is common among Korean enterprise ASes of this vintage that sit behind a dual-stacked national carrier.
