About this network

What it's used for

• Fibre and cable home internet, plus IPTV, for South Korean households.

Notable

• A large "eyeball" network: addresses here are consumer home connections, not servers.
• SK Broadband is a top-three Korean fixed ISP alongside KT and LG U+, and the fixed-broadband arm of mobile carrier SK Telecom.

Interesting

• It grew from the former Hanaro Telecom, one of Korea's early broadband pioneers, into SK's fixed-line business.
