Quote from: Guru on September 28, 2012, 10:49 pmThe problem with making up an address is that the Internet name spaces have become so crowded (particularly the dot-com domains) that almost everything you can think of has already been taken by someone. I got caught by this some time back. I used to be in the habit of using localhost.org for a domain, thinking that it was most likely unresolvable, and therefore ok. One day I had a brainwave, and decided to check it out. Sure enough, some miserable rotten prick had registered localhost.org! <Sigh>You can use example.com, example.net and example.org. They're all registered to ICANN, but there are no MX records and there is no mail delivery. The domains are placeholders because they're used as examples in the RFCs.
