What it's used for

• The address space carries residential broadband traffic, indicated by the consistent netname broadNnet-KR across all sampled prefixes.
• The AS announces 96256 IPv4 addresses across 72 prefixes while maintaining only 1 observed neighbour, a ratio that identifies it as an access network rather than a transit provider.

Notable

• All registrants for the largest prefixes are listed as IRT-KRNIC-KR, which aligns with the announcer's identity as a major South Korean cable operator.
• The inventory consists entirely of IPv4 space with no IPv6 prefixes announced, reflecting a legacy or IPv4-centric deployment strategy.
• The address inventory is finely subdivided into numerous /20, /21, and /22 blocks, typical of a large-scale consumer ISP managing distinct customer segments or regional nodes.
