Blocking all ip's but my own

[rfontaine]

I am creating a new website and want to block every ip address but one (my own) in .htaccess.

What is the best way to do this?

[Span]

Not saying that this is the best way to do it, but it should work.

RewriteEngine On
RewriteCond %{REMOTE_ADDR}!^22\.33\.44\.55$
RewriteRule .* - [F]

Reads like: IF the visitor's IP address not matches "22.33.44.55", THEN serve a 403.

Hmmm...

Throws an Internal Server Error - but I know RewriteEngine On works

[Span]

It's been a while since I posted here, so obviously I forgot to say there must be a space before the exclamation mark:

RewriteCond %{REMOTE_ADDR} !^22\.33\.44\.55$

Could it be that?

[rfontaine]

Yes Span, you fix the error. Thank you very much!

Or you could do

Order deny,allow
deny from all
allow from 100.100.100.100

in .htaccess

No need for mod rewrite.
