iOS-Android difference

[itzikfoc]

Hi

While on Android when using "lookup.Query(SomeEmail, QueryType.MX)"
im getting IDnsQueryResponse.HasError equal true,
but when in iOS im getting (for the same email and setup) HasError equal false, but with IDnsQueryResponse.Answers collection empty.

Why is the difference in behavior?

Replies you get depend on your network and most importantly the DNS server the request is sent to.
Without more information, I cannot really help you.
If you find out what DNS server each device uses, you can just manually check for the reply with common dns tools.

If the server isn't the reason, could be that there are differences in the networks your devices are using and that dns requests might be blocked by some firewall or proxy?...

1. Im checking if it was tested with both devices connected to the same network, but i believe the answer is yes.
2. Im using LookupClientOptions(IPAddress.Parse("8.8.8.8"), IPAddress.Parse("8.8.4.4")).
