It'd be a lot easier to just write down the IP. Nobody is going to actually remember those words, and if they're on a shared IP it's not going to get to them anyhow.
And if they change IPs (because their host shut them down because the government forced it) then the 4 words are worthless.
Agreed. In fact, DNS was developed basically to address many of the problems with this (admittedly cute) idea :)
Its ancestor was basically a system where'd you download a new hosts file every day -- which was doable when the Internet was small, but didn't scale well.
It's a nice idea, though the word list may be refined a bit, and there could be larger word lists and something that takes account of nouns/verbs to create more cohesive sentences.
I suspect we are more likely to see splinter DNS networks get set up and people will just learn how to add these servers to their configs for name resolution...
Can also see a future where the public Internet is deemed completely untrustworthy and everyone just connects with trusted parties over VPNs....
I suspect even more that nothing will actually happen. People know there's risk in running torrent sites, they bet the ad revenue will outweigh it and eventually they lose.
Of course it's actually easier to use bgp to hijack and blackhole a route for an IPv4 address than it is to get new nameservers inserted for a specific domain at the roots. If folks moved to rely on a system that didn't involve lookups, it would become even easier to take them down.
technically no, but practically yes - most implementations discard routes more specific than a /24 to prevent their routing tables from becoming unmanageable.
Stealing a /24 is an awful amount of leverage in convincing the ISP to disconnect a /32 as long as you have enough pull to ensure large networks will continue to respect your routes.
And if they change IPs (because their host shut them down because the government forced it) then the 4 words are worthless.
