Summary
NIX.CZ
ixp transit czechia
NIX-DR is operated by NIX.CZ z.s.p.o.
What it's used for
- The space carries the Neutral Internet eXchange (IXP) infrastructure for Czechia, as indicated by the registry holder and the single announced IPv6 prefix
2001:148f:fffc::/48. - With 0 IPv4 prefixes and 1 IPv6 prefix announced against 21 observed neighbours, the high neighbour-to-prefix ratio indicates a transit or peering role rather than an access network.
- Traffic from this AS consists of peering sessions and transit flows between Czech and international internet service providers connecting at the exchange.
Notable
- The registrant NIX.CZ z.s.p.o. matches the AS handle
NIX-DRand the announced blocks in Czechia. - NIX.CZ is the largest neutral internet exchange point in the Czech Republic, founded in 1996 to facilitate interconnection among ISPs.
- The address inventory is minimal, consisting of a single /48 IPv6 block with no IPv4 space, typical for an IX provider that relies on customer-announced prefixes for most traffic.

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: 440 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.
