The range for regression is https://github.com/dotnet/runtime/compare/a09ad529...10ee2b11. Possibly related to https://github.com/dotnet/runtime/pull/107241, @wfurt could you please check it out?

[wfurt]

it is likely @matouskozak. At least the test was added there. It seems like Android injects something there. I guess one option would be to simply skip this test on Android. Any thoughts on this @simonrozsival ?

[simonrozsival]

@matouskozak @wfurt this seems to be the default value on Android. I am not sure if this is the default/fallback value in the bionic libc or if Android calls setdomainname("localdomain") and it is a valid value. I think we should just skip this test because Android.

[wfurt]

I look at the test again @antonfirsov and I think we should update the assert to expect the localdomain on Android. I think I would prefer that over disabling the test.

Fixed in https://github.com/dotnet/runtime/pull/110070, thank you @antonfirsov
