IP-Host Auto Header - browsers extension/add-on

Supported browsers: Firefox, Opera, Chrome, Chromium

The IP-host Auto Header extension allows you to create a list of IP addresses and their corresponding hosts. Hostnames assigned to the IP address are then automatically appended to the request in the HTTP "Host" header if a connection to the given IP address is detected. This enables automated access to servers using their IP addresses and a prepared list against domain names. The list of IP addresses / hosts can be exported / imported from a JSON file.

Features:

• easy to use
• provides access to websites via an IP address
• provides access to websites during DNS failure
• allows you to create your own list of IP addresses and their assigned hosts
• automatically detects if the requested IP address is on the list
• automatically includes the appropriate HTTP Host header to the request
• allows you to import / export a list of IP addresses and hosts
