@ symbol:
In actual fact, everything between "http://" and "@" is completely irrelevant! Just about anything can go in there and it makes no difference whatsoever to the final result.
This feature is actually used for authentication. If a login name and/or password is required to access a web page, it can be included here and login will be automatic.
Example<EMAIL_ADDRESS>But if the page requires no authentication, the authentication text is in effect ignored by both browser and server.
the @ symbol can be represented by its hex code %40 to further confuse things; this works for the IE browser, but not for Netscape.
Number format equivalency
Merely using an IP address, in its usual dotted-decimal format, in place of the name is commonly done and can be quite effective at leaving the human reader in the dark about which website he's visiting.
But there are other ways to express that same number. The alternate formats are:
"dword" - meaning double word because it consists essentially of two binary "words" of 16 bits; but it is expressed in decimal (base 10);
"octal", meaning it's expressed in base 8; and
"hexadecimal" hexa=6 + deci=10 (base 16).
The dword equivalent of <IP_ADDRESS> is<PHONE_NUMBER>.
Mix of all
Ah, you thought you had it all nailed down? Well, it's mix-and-match time!
Believe it or not, the following URL, which uses hex, decimal and octal numbers in the IP address, actually works: http://0xCE.191.0236.0x37/obscure.htm
This mixed-format address also works with bogus authentication text<EMAIL_ADDRESS>For Netscape users, omitting the hex is necessary; but decimal and octal can be mixed<EMAIL_ADDRESS>Less Dots
A variation on the dword IP address is one where a portion of the IP address is similarly converted. This only works with the rightmost two or three numbers, not the leftmost.
Let's start again with <IP_ADDRESS>. Leaving the "206" as it is, we do the same calculation with the last three numbers:
191 * 256 + 158 = * 256 + 55 = 12557879
Now we have: http://206.12557879/obscure.htm
158 * 256 + 55 = 40503
Which results in: http://206.191.40503/obscure.htm
Now extend this same concept to hex and octal numbers:
http://0xCE.0xBF9E37/obscure.htm
http://0xCE.0xBF.0x9E37/obscure.htm
http://0316.057717067/obscure.htm
http://0316.0277.0117067/obscure.htm
Why not mix and match?
http://0316.0xBF9E37/obscure.htm
