[sudo-users] Query on Host Alias

Hi Linux Gurus,

I Have very basic question, Why do we need to configure host alias in
sudoers file. My understanding is Sudo is not a centralised utility where we
can configure privileges for all servers using one file from a single
server. if you want to configure privileges using sudo utility you need to
configure on that particular server for the users on that server.

If my understanding is correct, I really don't understand configuring host
alias in the sudoers file, does hot alias work as access control list  or I
am completely thinking wrong.

can anyone let me know why host alias is used and what is the purpose of
using it in sudoers file.

Thanks in Advance.
