A bug has been detected where some records in the answer are excluded from the output. Should be investigated further.

MuhammedReza07 commented 1 year ago

Maybe it was a wrong observation, since I was both sending NS and A queries?

Resposne from Google's DNS server, IP: 8.8.8.8.

Unable to replicate issue, more information when the issue returns.

MuhammedReza07 commented 1 year ago

It seems like this issue stems from opening and closing the terminal or something like that after writing the data to it. Nothing indicates that there are any "real" issues with the code.

Issue closed.
