About this network

The AS handle CNGI-BJ-IX4-AS-AP is held by CERNET2 IX at Beijing University of Posts and Telecommunications.

What it's used for

• The space carries IPv6 prefixes associated with the CERNET2 Internet Exchange Point, including 2001:250:20b::/48 and multiple 2001:da8::/48 blocks.
• With 71 IPv6 prefixes announced and 2 observed neighbours, the low neighbour count relative to the prefix count suggests a peering or exchange role rather than a transit provider.

Notable

• The registry holder name explicitly identifies the operator as the CERNET2 IX at Beijing University of Posts and Telecommunications.
• The address inventory consists entirely of IPv6 space, with no IPv4 prefixes announced or in inventory.
