Wrong update in etc/hosts?

Linux and Unix-Like Ubuntu
1

Hi All
I have just updated the /etc/hosts file in my machine ub1 following setup of a library I need to install.
The thing is that my machine is ub1 and I don't know what might happens commenting the line 127.0.1.1 where ub1 is already defined.
Might I hurt some functionality doing this?
Thanks all

127.0.0.1   localhost
#127.0.1.1 ub1 # is this commenting bad?
10.5.1.183 ub0
10.5.1.189 ub1
