add NAT IP to hostname

[joe_91]

We have some NAT ip that we want to add to the hostnames in /etc/hosts will this work

hostname current-ip nat-ip
sharky (ex.69.4.213.108) (ex.10.9.66.55)

Thanks

Joe

It's not the correct sintax, the correct sintax will be:

current-ip hostname alias
nat-ip hostname-nat alias-nat

You should not use the same host name for multiple ip address in the hosts file.

NAT provides a special address outside your computer and since you cannot assign two or more IP addresses to a single hostname, you'll have to create a new hostname, perhaps sharknat or something similar. If you cannot change entries in your DNS server, you'll need to change your /etc/nsswitch.conf file so that /etc/hosts is consulted first, then your DNS server(s). Change the hosts line to read:

hosts: files [NOTFOUND=continue UNAVAIL=continue] dns

Then add the IP address and new-hostname to /etc/hosts. Use nsquery to verify:

nsquery hosts new-hostname
