About this network

MODMC-54103-AS is held by MOD Mission Critical, LLC.

What it's used for

• The address space carries colocation and managed infrastructure, evidenced by netnames such as CAC-BLOCK5 and MOD-MISSIONCRITICAL, and reverse DNS entries pointing to rdns.ColocationAmerica.com and colocationamerica.com.
• The AS announces 114,688 IPv4 addresses across 179 prefixes and 4 IPv6 prefixes, while maintaining only 11 observed neighbours; this high address-to-neighbour ratio indicates a hosting or data center role rather than transit.
• Traffic from this AS consists of web/API endpoints, managed servers, and hybrid cloud workloads for enterprise clients, consistent with MOD Mission Critical’s business as a managed services provider specializing in colocation and IP services.

Notable

• Registrants include MOD Mission Critical, LLC, Colocation America Corporation, and Internet Utilities NA LLC, with the latter two representing historical or leased blocks within the current announcement set.
• The address inventory is finely subdivided into numerous /21 and /22 blocks, reflecting a site-by-site segmentation typical of a multi-POP data center operator.
