  • They dont have a rough idea, they have a very accurate picture of where they should send a packet based on the IP address.
    Routers at the internet-backbone scale actually announce the IP addresses they are responsible for, as well as other routes (with an additional path cost added) that they can reach.
    So, they match a destination IP to the most accurate IP block in their routing table (so a destination of 8.8.8.8 with 2 entries of 8.8.8.0/24 and 8.8.0.0/16, it will match the 8.8.8.0/24 route) and forward the packet to the router that announced it.

    Routing at the internet scale is much smarter than routing at the home (even business) level














  • Uft, imagine if that happened and musk chose a single unicode character as the domain?!
    Unicode are already sanitised from domains, because there are ubicode characters that look like - but are distinct from - ascii characters… which opens a huge pandoras box of MITM attacks of malicious sites on domains that visually look the same as legit domains.

    If musk wants a single unicode character, all the browsers are going to have to figure out that can of worms
