Ok, but you can always browse by IP address and in this case there
is no DNS server than can stop you from browsing what you want.

Vaguely related, are host headers - a lot of webservers share an IP
address/many IP addresses and use host headers to 'display' the
correct website.

You wouldn't be able to browse a particular website hosted in this
fashion, by IP address.

If you know the website domain and the corresponding IP address and if
your ISP prevents you from accessing this website by timing out or
tampering DNS query results you can always put the entry like

192.168.10.20   www.domain.tld.

to your hosts file and access the site.

This technique is also in use when someone needs to access the site
which is on a not delegated domains.


Even this way, you should know all the IP of subdomains to work properly. Try it for facebook, open homepage fine but once you login it will fail. Another thing, we are talking about a technical person, for other users they don't know about hosts file or they don't have access to change it even it they know about it.

regards.
