I saw many different /etc/resolve.conf configurations on the net. Some of them have just nameservers listed, some of them have 'search local.localhost.net', some of them have 'round robin' parameters... etc.
What are the best practices for /etc/resolv.conf file on Ubuntu?
EDIT: This is machine running Ruby on Rails Web server with Apache front end. The server has occasional access to Google Data APIs.
So the questions are:
- Should I use google DNS servers or server provided by my hosting?
- Should I have anything else additional to nameserver entries?
I understand there are manuals but I'm confused why different cloud providers (Rackspace, SoftLayer, etc) have different configurations.
