This is a question that might require a bit of “prior knowledge” in order for an answer to make sense.
Basically computers keep track of each other with complicated, unique numbers. This isn’t easy for humans to deal with so instead we have websites like netflix.com. DNS is a system that translates “netflix.com” to it’s more complicated unique computer address so that your computer connects to the netflix server when you type in that web address.
There are a number of servers (DNS Servers) on the Internet with databases that keep track of which website has what computer address. Usually, the company (ISP or Internet Service Provider) that you get Internet from has their own DNS Server and tells your modem to tell your computer or phone to use that server to look things up when you browse the web, but it is possible to use alternative servers.
Technically, the system is very trust-based - it’s just assumed that they are going to respond accurately and in good faith. It is possible to mess with this but there are other layers of security and authorities your computer should be using to make sure that you are actually visiting the website you think you are visiting. Usually ISPs just use this server to keep track of the websites you visit so they can sell your data to advertisers.











Out of curiosity, in what way do you mean they are being more like Rs? I’m hoping you are not referring to their attempts at matching the R’s redistricting tactis.
