WorldIP is a useful network add-on for Firefox.
What it does is provide a whole lot of useful network information related to websites. This includes the IP address of the server which hosts the website/domain, the datacenter, provider and autonomous system (AS) details, DNS records information, country where the domain/website is located. Besides that, it even provides information about own (user’s) public IP address, provider details if needed.
How this works is whenever this add-on is active, it will randomly query a list of public DNS servers so as to get various related information like DNS records, IP detailsÂ and so on. Also, geolocation of server and datacenters for the website is accurately obtained by querying the WIP database (this is through https so it is encrypted). During this whole process, there is no slowdown when browsing websites because this process is asynchronous.
