What is the advantage or the purpose of having more aliases for hostname?

[@cloudpatashala]

There might be more disadvantages than advantages.

[@dropdcsc]

if government bans some site can we access it by resolving domain name to IP address in /etc/hosts

[@cloudpatashala]

Yes that would work.
Unless govt denies those ip addresses on firewalls
