Demon's homepages service was based on IPv4 virtual hosting and had IIRC a /16 and two /18s allocated to it. It was a single web server with a few reverse proxies that took most of the load and that also had all the IP addresses. The Irix version used a cunning firewall configuration to accept connections to all the addresses without stupid numbers of virtual interfaces; the BSD version used a kernel hack. http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/12071 On the web server we stuffed the IP address into the filesystem path name to find the document root. (Or used various evil hacks to map the IP address to a canonical virtual server host name before stuffing the latter in the path.)
