About this network
AS9577 (KYOBOTRADE-AS) is held by Kyobo Securities Co., Ltd., a Seoul-based brokerage and investment bank offering securities and derivatives trading, underwriting, corporate finance, asset management and wealth management. It is a financial-sector enterprise AS, run for the firm's own trading and client-facing systems rather than sold as a service.
What it's used for
RIS observes 3 IPv4 prefixes totalling 768 addresses (203.239.34.0/24, 211.234.59.0/24, 220.78.134.0/24), no IPv6, and 4 BGP neighbours. Three unrelated /24s taken from three different ranges, multi-homed to four peers, is the standard build for a securities firm: the addresses are the stable, allow-listed endpoints for retail trading platforms, HTS and mobile trading apps, market-data feeds and links into exchange and clearing infrastructure, and the multiple upstreams exist because a routing outage during market hours is a business incident, not an inconvenience. Four neighbours on 768 addresses is a redundancy ratio you only see when uptime matters far more than volume.
Notable
- Reverse DNS on the sampled addresses in 203.239.34.0/24 returns generic customer.epnetworks.co.kr records. Those are a Korean provider's default PTRs for customer space, so they say where some of the network is homed, not who holds it. The AS itself remains registered to Kyobo.
- Kyobo Securities is listed on the Korea Exchange (ticker 030610) and sits within the wider Kyobo group.
- As with most brokerages, the public address footprint is only the exposed edge; the trading and settlement estate behind it is private and never appears in BGP.
