About this network

BROAD-RUN-BORDER-AS is operated by Verisign.

What it's used for

• The address space carries internal infrastructure for domain name registry services, evidenced by reverse DNS entries such as coreui.verisign-grs.com and hostnames under brn1.verisign.com.
• With 12,288 IPv4 addresses and 11 IPv6 prefixes announced across 35 IPv4 prefixes, and only 8 observed neighbours, the inventory reflects a finely subdivided internal corporate estate rather than a transit or access network.

Notable

• Registrants consistently identify as Verisign entities, including "Verisign Infrastructure & Operations" and "Verisign Global Registry Services," aligning with the announcer.
• Verisign is a global provider of domain name registry services and internet infrastructure, enabling navigation for many of the internet's most visited websites.
• The address inventory is dominated by /23 and /24 blocks in the 72.13.0.0/16 range, with additional space in 64.6.0.0/16, 199.16.0.0/16, 209.112.0.0/16, and 216.168.0.0/16.
