About this network

CTBTO-AS is operated by the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization.

What it's used for

• The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable
