// Hostname cloaking (+x mode) module for inspircd.
// version 1.0.0.1 by brain (C. J. Edwards) Mar 2004.
//
// When loaded this module will automatically set the
// +x mode on all connecting clients.
//
// Setting +x on a client causes the module to change the
// dhost entry (displayed host) for each user who has the
// mode, cloaking their host. Unlike unreal, the algorithm
// is non-reversible as uncloaked hosts are passed along
// the server->server link, and all encoding of hosts is
// done locally on the server by this module.
