About this network

The AS handle SKB-GOV-KR is held by SK Broadband Co Ltd.

What it's used for

• The address space carries residential broadband traffic, indicated by the consistent netname broadNnet-KR across all sampled prefixes.
• With 44,544 IPv4 addresses announced across 25 prefixes and only 7 observed neighbours, the high address-to-neighbour ratio implies this is an access or eyeball network rather than a transit provider.

Notable

• All registrants in the RDAP sample are listed as IRT-KRNIC-KR, which aligns with the announcer's identity as a major South Korean telecommunications operator.
• The inventory consists entirely of IPv4 space, with no IPv6 prefixes announced, and is concentrated in the 125.61.0.0/16 and 175.122.0.0/16 ranges.
