The folks at Apple and Cloudflare are trying to further protect your privacy. The duo is releasing a new internet protocol called Oblivious DNS-over-HTTPS, or ODoH for short. The goal is to make it more difficult for your Internet Service Provider (ISP) to keep track of which websites you visit.
In simple terms, when you go to a site on your phone or computer, your web browser uses a domain name system (DNS) resolver to convert the website into an IP address, which is then used to find out where the site is located located. on the Web. Think of it as traditional snail mail. You can̵
Currently, this process is not encrypted, which means that your DNS resolver – which normally goes to your ISP by default unless you’ve changed it manually – can record which sites you visit if they choose. And they usually do, since most ISPs already sell your browsing history to third-party advertisers.
ODoH tries to prevent this by disconnecting any DNS hits from the user himself. It does this by introducing a proxy that resides between you and the DNS server. Think of it as using a virtual private network) VPN. But instead of falsifying your location and IP address, which could theoretically be fed back to you if someone tried to figure it out, ODoH makes sure your DNS doesn’t know who made the request. It only knows which sites have been requested.
So if a significant number of people are going to use ODoH, the DNS server will only see one huge blob requesting sites rather than some individual ones. Cloudflare has already added support for ODoH requests through its 188.8.131.52 DNS service. Unfortunately, you will have to wait for your browser, operating system (OS) or both to support it.
Currently, only Firefox from Mozilla has implemented the feature. Hopefully more will come on board, especially since a lot of people work from home. Internet privacy is more important than ever before.
