Users did report that visiting a web site via iPad/Safari fails. I found out that the reason a failing DNS query. This issue only applies to some websites (for others it works). Visiting one of the "failing" sites at the same time using an iPhone works.

E.g. one of the failing sites is achgut.com. I recorded a network trace on the router. In this trace I see a lot of succeeding DNS queries from 192.168.178.109 (an iPhone). I see some other queries from 2003:ec:df10:1600:f419:5a6c:e4bc:f28e but I am not sure which device this is. The 192.168.178.109 is a MacBook.

I would like to know if the DNS query of failing iPad did actually reach the router. Unfortunately I do not know the ip address of the iPad.

My questions are: Is there a way to identify the device in the trace? Does the trace indicate any DNS errors?
