Unbound Incorrect Github ressolving

[gjf]

Hi.

I am using Unbound addon in my home network.

From some time I observed github.com does not open, also pings are lost.

Invetsigating this issue I found the website opens OK when using VPN. I have contacted my provider and he told me he can open github.com without any issues.

Further investigation shows github.com ressolves as 140.82.121.3 in my home network, but the correct one (providrer's and VPN's) is 140.82.121.4.
By the way https://140.82.121.4 really opens github (but shows certificate mismatch of course).

I can hardcode github's IP, but any idea why Unbound ressolves IP incorrectly?

Case is closed: ressolve is OK (both "3" and "4" belongs to github), but it's Skynet issue.
