Was passiert wenn man PiHole ausschaltet?

frager176Byfrager176

Hi, ich will mir einen PiHole aufsetzen aber denke über folgende Probleme nach:

  1. Liest der PiHole nicht die Daten mit wenn er die DNS Anfragen bearbeitet bzw. filtert?
  2. Was passiert wenn der PiHole mal ausgeschaltet ist, weil ich den Pi für was anderes nutze, funktioniert das Internet dann trotzdem oder nicht weil ich den Pi als DNS Server eingestellt habe
  3. Was passiert wenn ich den Pi für was anderes benutze?

Es wäre cool wenn ich auf diese Fragen antworten bekäme.

  1. PiHole only reads inquiries, but not addresses.
  2. Depending on your settings on the PC/device or router, if you have set an alternative DNS server, then not much happens and your devices can continue to go to the Internet or Send inquiries if you have only entered the PiHole as a DNS server and no alternative server if it is no longer accessible (e.g. 8.8.8.8 or 1.1.1.1) then you will not get into the Internet with any device
  3. If you delete the Pi and then don’t run PiHole anymore, your devices may come. no longer eat internet and otherwise you can use the Pi for other things.

If you haven’t got a Pi yet, check out Mini PCs with AMD Ryzen 5500U or Intel Pentium N5000 series, which you get mostly for 100-300€, have a similar power consumption as the Raspberry Pi, an SSD and often more RAM, i.e. are significantly more powerful and fail-safe than a Raspberry Pi. For example, Proxmox can then be installed on these devices as a hypervisor/visualization server and several virtual machines can be installed and thus several servers can run on one device.

Does the PiHole not read the data if it processes or filters the DNS requests?

PiHole as a DNS server obviously works with the DNS requests and forwards them if he cannot use them himself.

Simply put, however, this is only the translation from the readable domain to the IP, via which the service is provided. The data of the connection itself do not run via the PiHole

What happens when the PiHole is turned off because I use the Pi for something else, the Internet works anyway or not because I set the Pi as a DNS server

The Internet continues to work. You will only get problems with DNA resolution unless the result is temporarily stored in the system.

For the lay people, it looks like the Internet doesn’t work.

What happens if I use the Pi for something else?

You can also run more than one service on the Pi.

Otherwise, the Pi is set as a DNS server and cannot be reached, DNS requests cannot be resolved. If you want to turn off the DNS server completely at some point, you will have to set another DNS server again

Of course, the PiHole reads the DNS requests. But he’s in your network. Otherwise you will send the DNS requests elsewhere, and they will also read.

No, it doesn’t work. The joke is that he leads requests for sites to the void you don’t want to get.

If you do not use the Pi as a DNS server, you need to configure the DNS in your home network differently as it was before and renew the DHCP Leases.

So if the Pi is working out DNS doesn’t work but you can somehow adjust the whole thing that if the Pi is offline you then use another DNS server

Yes, you have to enter an alternative DNS server in your Fritzbox (or if not possible, in your PC/phone etc., but in the Fritzbox is the better solution because then the settings are automatically passed on to your devices)

If you use 2 different DNS servers in the router or on the computer, both DNS servers are used alternately, not only the first!

That depends on the router. Of course you can.

Some FRITZ!Boxes have the option to use the DNS servers of the Internet provider if the configured DNS servers are not accessible,

then the internet continues to work if the pi is not accessible, but then again with advertising.
