Function hash_inaddr

server/vhost.c:352–356

This hashing function is designed to get good distribution in the cases * where the server is handling entire "networks" of servers. i.e. a * whack of /24s. This is probably the most common configuration for * ISPs with large virtual servers. * * NOTE: This function is symmetric (i.e. collapses all 4 octets * into one), so machine byte order (big/little endianness) does not matter. * * H

 * Hash function provided by David Hankins.
