Hi guys, 1. which ip address should i be using in my hosts file...my servers external one or it internal one? All the tutorials talk about server ip addresses but i cant seem to work out which one its meant to be when on google cloud. 2. Also, the perfect server setup hosts file is different to mine on the very first line. Do i add the exact words "localhost.localdomain" or should it be "localhost.mydomain" or do i leave mine the way it is on a production webserver that will host multiple websites with unique domain names? Here is the perfect server hosts file... 127.0.0.1 localhost.localdomain localhost 192.168.1.100 server1.example.com server1 # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters Below is my current hosts file 127.0.0.1 localhost 35.189.x.x server3.<mydomain>.com.au server3 # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts 169.254.169.254 metadata.google.internal metadata 3.What issues would i experience if i left my current hosts files as is?
