Is resolve.conf read at boot time or real time

[columb]

We're amending our network and one of the things which is changing is the list of DNS servers

The simple fix is to amend /etc/resolve.conf - do I need to restart the networking service as well?

Err...
For resolve.conf read resolv.conf!

I'm fairly certain it's read in nearly or literally real time. You can test this by running a ping by name with a valid resolv.conf, then alter/blank resolv.conf and try the same ping immediately without restarting networking.

Restarting the network service is really a pretty rare event under normal operations, IMHO.

Thanks thedaver - not just for the info but for the test method as well. I'll post the results of the test as and when.
