Okay I cant understand this, when I try to ping to a machine on my network using the name associated I get a response from that machine, thats normal..
But there are messages that the sender sends to the top machine (SOA) that I dont understand.. First he sends a type A and gets a response with the IP associated to the name used on the ping command, but after that.. the sender only sends (before each ping) messages of type PTR to the (SOA)
Saying this: Standar query 0xf66c PTR 22.214.171.124.in-addr.arpa
and SOA respond with: Standard query response 0xf66c No such name
And before each ping they do this, I dont know why... I notice this using wireshark, thanks alot again for accept me here, being able to get some answer :)
