World IP allocation based on Hosted Domains

World IPs

The following is an IP mapping of domains in the COM, NET, ORG, INFO, BIZ, US space. The number of domains that resolve to which network addresses. Each network address coincides with an authority for that block, usually that authority resides in just one continent. A Network Block also goes by the name Class-A network. Blocks with fewer then 50 domains have been set to zero for simplicity. Domain owners may map DNS of their domain to any IP, but the domain will not resolve if the IP is in a dead zone.
