Need help for static IP configuration

Configuration
1

Hello from Vienna,

since beginning I’m using; http://homeassistant.local:8123 to get access to HA. As my network system, Openmediavault is using a static IP and since then no access issue, I want the same for HA.

My router has a DHCP range from 100 to 199, So for HA I will use (IPv4):
static IP: 192.168.0.250 → above DHCP range
Gateway: 192.168.0.254 → default from my router
DNS: 213.33.99.70, 80.120.17.70 → default from HA

So I have two questions:

  • do I have to add /24 for netmask?
  • can I use the DNS default from HA?

Thx for your help
Rudi

Here’s a copy of my Network config within Home Assistant in case that helps:

I have the netmask included as you can see.

The DNS servers are not associated with HA, you can use whatever you want e.g. your local ISP, Google, Adguard/Pihole, or Cloudflare as I use.

Hope that helps.

Thany you very much for your detailed answer. Unfortunately it did not work. I have changed according to my post:
static IP: 192.168.0.250
Gateway: 192.168.0.254
DNS:80.120.17.70

pushed the save button and nothing happened. The save animation did not stop. After some minutes I closed HA and did restart. Now I could see at network the new settings, but have to open HA in the old way…http://homeassistant.local:8123/

somehow strange…

But HA can be reached still under: http://homeassistant.local:8123/ only.Angy IP scan shows me that HA is located at 192.168.0.250…

Any idea
