What is difference between DNS Resolver and DNS Forwarder?

[emammadov]

Hello,

I am new to pfSense. Could you please clarify me in simple way that what the difference is between DNS Resolver and DNS Forwarder?

Thanks in advance.

So now we are google ;)

Its quite simple really a forwarder Forwards!!  Ie you ask for www.google.com, it forwards that to some other dns server, ie say your ISP which could in turn forward again until it finds a resolver that can actually resolve it.

A resolver walks down the tree from roots to find the authoritative nameserver for the domain your looking for in the above example google.com and asks it for the record www.

So first it asks roots hey how is NS I can ask for .com, thanks - hey NS for .com who is a NS I can ask for google.com - hey thanks, hey NS for google.com what is the A record for WWW - hey thanks.

Have you at least tried to search the forum?
Probably not, you would be posting in the "DHCP & DNS" section otherwise.

Here are the search results for a simple "forwarder resolver" query from the search button somewhere ^up there:

And here's the exact same question already answered:

Why do you think that other forum members should do your work? Honestly, I don't get that!

I was  going to respond to this query earlier but then thought better of it.

You've set the precedent so yes now you are… "Hello computer..."

A work colleague was my personal Star Trek computer for a while with his "smart" phone.  At lunch if I wanted to know something I'd just say "I wonder what blah blah blah?" and he would look it up.  Not quite as quick as the Star Trek computer, but pretty effective.

heheeh - yeah got a couple of guys at work like that ;)  You talking about something and they just break out their phones and look it up for you.  Saves battery letting them use their phones vs yours - hehehe
