Delegations, stub zones and forwarders

cbriant

Hi,

I'm really struggling to get my head around when to use a stub zone over a delectation, etc.. Does anyone know of a good article on the web which explains this clearly?

I'm learning this at the moment as well, but from what I understand, they are both used to make other domains aware of each other. The problem with delegations is that they must be updated manually while stub zones contain SOA records that allow them to detect when there are changes, so they can update automatically. I'm not sure if that's an oversimplification or not.

Here are a couple of links:

Not an oversimplication, you're correct. It's simple really. Delegations = static while Stub Zones are dynamic. Stub Zones are basically a dynamic delegation. You'd only really use a regular delegation if you want more control over what DNS servers are being hit on the target zone.
