NullReferenceException when using DNS to get the IP of an existing domain which has no A record

[dotada]

Area of Cosmos - What area of Cosmos are we dealing with?

Networking

Expected Behaviour - What do you think that should happen?

Returned null

Actual Behaviour - What unexpectedly happens?

Crashes with NullReferenceException

Reproduction - How did you get this error to appear?

Minimal reproduction sample below

using (var e = new DHCPClient())
{
    e.SendDiscoverPacket(); // since this is a minimal sample we'll just assume this successfully fetches an IP
}
using (var e = new DnsClient())
{
    e.Connect(new Address(1, 1, 1, 1));
    e.SendAsk("googler.com"); // fine until here - this is one of the domains where if I nslookup it from powershell it doesn't return a non existent domain but it also doesn't return an IP
    Address destination = e.Receive(5000); // crashes here with a CPU exception
}

And if anyone is wondering it isn't the timeout causing the crash as it crashes in way less than 5 seconds

Version - Were you using the User Kit or Dev Kit? And what User Kit version or Dev Kit commit (Cosmos, IL2CPU, X#)?

can you try google.com instead of googler.com?

[dotada]

Yeah, google.com works fine but I was testing if, say, I made a typo in the command and happened to hit that because in my actual code the domain is user inputted

you can add try catch statement, as it crashes with C# exception and not the cpu exception

My bad, I forgot to specify that it does crash with the CPU exception.
