Talk:Localhost

Can someone put something about what this is useful for? Thanks! Mark Richards 19:02, 11 May 2004 (UTC)
One use of localhost is in connection scripts where a SQL server may reside on the same system that is trying to connect to it. A PHP connection script example:
$hostname = "localhost";
$database = "DatabaseName";
$username = "root";
$password = "password";
$connectString = mysql_pconnect($hostname, $username, $password) or trigger_error(mysql_error(),E_USER_ERROR);
Rather than specifiying the IP address of the server in the script, using localhost is more dynamic since it will ALWAYS refer to the local machine even if you change the IP.
Another use the localhost reference is to test a Network Interface Card or NIC or your TCP/IP stack. A command line example:
Ping localhost
The result is pinging yourself. If no response is received there is a problem on the local machine not the network you may be working with. If you were to talk to yourself you would be considered a schizophrenic, with your comptuer on the other hand it may be desirable.
Hope these help!

Why 127
Does anyone know why specifically 127.0.0.1 is the address of the local machine?
What’s so special about 127?
I would have thought 0.0.0.1 for example would have been the most logical choice or maybe even 1.0.0.0
- Note that 127 in binary is 01111111... maybe it's got something vaguely to do with that?
theres no way this is differnt for anyone else right the local host is always that right o.O
just had an argument with a n00b and hes telling me im wrong and his local host always changes >.>;;
message me on king.testament@gmail.com about this k?
