About this network

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-DR and 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.
