AS25152 announces 1 IPv4 prefixes covering 512 addresses and 1 IPv6 prefixes.

About this network

K-ROOT-SERVER is operated by RIPE NCC.

What it's used for

• The space carries the RIPE NCC K-Root DNS server infrastructure, as indicated by the netname RIPE-NCC-K-ROOT and registrants RIPE NCC DNS Team and RIPE NCC Operations.
• The AS announces 512 IPv4 addresses across 1 prefix and 1 IPv6 prefix, while maintaining 425 observed neighbours; this high neighbour-to-address ratio indicates a transit or peering-heavy role rather than an access network.

Notable

• Registrants RIPE NCC DNS Team and RIPE NCC Operations align directly with the announcer, confirming internal ownership of the address space.
• The address inventory consists of a single contiguous IPv4 block, 193.0.14.0/23, and one IPv6 prefix, 2001:7fd::/32, reflecting a focused, dedicated infrastructure footprint.
