I have recently upgraded my Macbook to Big Sur and now the Lookup.run function is no longer working. The DNS lookup seems to timeout and then the function returns a null. This had worked perfectly fine for me when my Macbook was running Mojave.

I am using dnsjava v3.0.2 however I have also tried v3.3.1. I am also using Java SDK 1.8.

Please can I get some assistance.
