About this network

VNNIC-AS-VN is operated by VNNIC (Vietnam Internet network information center).

What it's used for

• The address space carries registry infrastructure, evidenced by the netname VNNIC-NET and registrant VNNIC IPHOSTMASTER associated with both announced IPv4 blocks.
• The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small-scale internal or registry-specific network rather than a transit or access provider.

Notable

• Registrants for both IPv4 prefixes are IRT-VNNIC-AP and VNNIC IPHOSTMASTER, which align directly with the AS holder identity.
• The address inventory consists of two /22 blocks in the 203.119.0.0/16 range and a single /47 IPv6 prefix, representing a compact and consistent allocation for the registry's operational needs.
