Your system uses resolvconf, so the resolv.conf file is replaced by a symbolic link to /etc/resolvconf/run/resolv.conf and resolvconf dynamically generated the file. That's why DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
To properly update the information in the file, you can put the dns-* parameters in /etc/network/interfaces e.g.
iface eth0 inet static
dns-nameservers 18.104.22.168 22.214.171.124
Then, you can update the dns-* info by
$ resolvconf -d eth0
$ resolvconf -a eth0
Or you can do ifdown & ifup and resolvconf -d, -a will happen behind the scenes.
Note: sometimes I find resolvconf -u doesn't work. I don't know why
You should read man resolvconf. There's more information about all this.
TIP: if you want to update /etc/resolv.conf manually, you can remove the symlink and create /etc/resolv.conf by hand. This way, the file won't get updated from resolvconf ever.
$ rm /etc/resolv.conf ;# to remove the symlink
$ vi /etc/resolv.conf ;# to create a regular file
