No local host after installing apache

I checked for localhost on my browser but it appears apache2 did not take effect there. I know its installed because I got this in terminal searching for it:

apache2-bin/xenial-updates,xenial-security,now 2.4.18-2ubuntu3.17 amd64 [installed]

I tried this but still didn't see locahost in browser:
sudo /etc/init.d/apache2 start
