They indeed support 2 ip addresses on the same computer, but 2 different default gateways is problematic unless you know how to play with metrics, and your os uses tables and connection tracking so connections coming in on 1 interface does not leave the other interface.. Linux can do that, I don't know about windows. However, putting a windows computer directly on the internet without private ip addresses is a big NONO security wise.

Why switch? I'm coming into this late so if my assumption about your hardware is incorrect then I apologize.
Can you put a second network adapter in your computer? on the motherboard, USB, etc ... Windows Linux and Mac all support multiple IP addresses on the same computer, even on the same adapter ...

Hello Marius.
Happy new year to you and yours!!! Stay healthy as long as possible!
One question.
I do have two diferent ISP's with two different static IP addresses.
At the moment, when I need, I switch from one to another by means ot two Isostat type switches with pushbuttons, each one with 4PDT fields.
It is not very convenient, mainly beacuse I have to stop computers ethernet card and re-start again in order to have DNS working properly.
I was thinking to use two 4PDT low voltage minirelays. But do not know if it will work properly.
Are you, by any chance, aware of any inexpensive electronic switch/solution for such setup, please?
Will appreciate very much your possible suggestions.
Best regards.
