Sharing an address does not always mean sharing a server: on a CDN or a large hosting platform, millions of unrelated domains answer on the same few addresses. We measured how far that goes in Half the web sits on 276 IP addresses. The complete list of neighbours, also for an IP address, comes through the API: reverse IP lookup.
