comment What determines the time to first ping response in an OS?
Obviously it is not the firewall that responds to ping nor is it the network card. If I am not mistaken, the card just places the Ethernet frames in a buffer for the operating system's TCP Stack/Driver to inspect and respond to. The firewall hooks into the TPC Stack to modify it's behaviour. i.e. to filter certain packets and/or to allow the TPC Stack to return or not return ICMP ECHO requests. I think you will find that the network card doesn't come into this discussion at all..

comment What kind of issues would occur if resolve.conf had no dns servers set?
I'm trying to gather the information about specific problems that will occur in order to make a case to someone that this is not a good idea. The answers which mention SSH reverse lookups failing are a good example which the customer would encounter when they first logged into their un-configured box.

It's a hosted server somewhat like an Amazon instance.

I would like this to be a turnkey system too, but I am gathering information of about what issues would occur in order to present a case to the decision maker that this may not be a good idea

..this is what I meant by "obvious inability to resolve hosts". I was thinking of other side effects that would not be so apparent. e.g. if the ntp settings included the host name then the time would drift.
