Summary

RIPE NCC K-Root Server

Netherlands · AI-generated

infrastructure dns root ncc

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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
