The following is a (partial) list of reserved names which can not be chosen as nodenames.
- net (used for community-run servers!)
- webmaster, admin, sysop, etc.
- dns, ns, ns0, ns1, etc.
- www, wiki, wind, dav, web, webdav, etc.
- mail, imap, mx, pop, pop3, etc.
- This list is not complete! So there may other names which may be misleading or reserved for similar reasons and which can therefore not be used as a nodename.
