I quick search hasn't turned up the info I'm after, so apologies if this has been covered and I have missed it.

How can I change the DNS server address that the Fritz DHCP assigns to clients?

Do you want to change the DNS servers on your PC (if so what type) or in the Fritz?

On the Fritz you go into control panel, internet, account information, dns server and change it there. In windows you hit start, type tcp, go into network connections, look in the properties of TCP.

I want to be able to make the Fritz assign a different DNS server via DHCP (not it's own address).

Not sure you can do that. You can have the Fritz use a different DNS server, but if you want your PC to use a DNS server other than the fritz you'll probably have to set it up manually. What you're asking isn't unreasonable, and it's no doubt possible with devices made for complex calculation, but maybe not a home router. You never know though, someone may know how.

Most cheap home routers will let you do this. I'd like to avoid assigning it manually on the devices.

What are you trying to achieve? You've said what you're trying to do, not what you're trying to achieve.

What's the difference between your computers talking to the Fritz and the Fritz talking to remote DNS server and the computers talking directly to the remote DNS servers? The Fritz just acts as a cache, latency is just about zero.

Just having some issues where DNS times out sometimes when using the Fritz as DNS server, but no problem when client is directly querying Snap DNS servers. So just want to bypass fritz DNS altogether, but with phones, tablets, laptops, guests, etc; I would like to do this via DHCP and not manually.

That's odd. Have you checked the Fritz log to see if it reports and problems? You'd have thought a dedicated device on the network should be pretty good, and DNS isn't particularly complex.

Nothing in the logs. I was just going to bypass the issue and not worry about it, but looks like that isn't going to be an option.

Most cheap home routers will NOT let you do this. It's something that's very rare.

As most routers these days all run Dnsmasq (or variants of this) they'll all hand out the router IP by default for DNS.

Out of curiosity is IPV6 disabled on the fritz? And if not, do so and see if your issues go away

Had similar case myself and with a recent mates install. Called asking if I knew why half the images on a page like stuff would not load, and certain aspects of FB failing.

Disable IPV6, and away it went. Seems to be the way it handles requests and firing them back in the particular protocols

I don't use a lot of cheapies, but I'm pretty sure the ones I've used in the past have let me do this. Regardless, the Fritz isn't the cheapest router out there.

Yep, that's already disabled.

You have to do this in the 'Internet Connection' part of the router. (i think that's where it was....)

I have done this for someone who wanted to get around some geo-blocks. I installed a Mikrotik router to be the DNS server which gave us better control of what went where.

Pretty sure the way to do it was under the internet connection settings just untick the 'obtain dns automatically' and choose the option 'manually assign dns'. Then just simply put in the DNS server you want to use (in my case an internal IP address) and that's it.
