The UDP object doesn't expose decoded DNS data if the sport or dport are 53. It just saves the data as this.data:
UDP
DNS
sport
dport
this.data
this.data = raw_packet.slice(offset, offset + (this.length - 8));
However, it does decode DNS in the toString() function:
toString()
UDP.prototype.toString = function () { var ret = "UDP " + this.sport + "->" + this.dport + " len " + this.length; if (this.sport === 53 || this.dport === 53) { ret += (new DNS().decode(this.data, 0, this.data.length).toString()); } return ret; };
Moreover, the pcap library doesn't export the DNS decoder for a developer to manually decode DNS.
pcap
Is there a way to get the decoded DNS packet from a UDP packet?
Thanks
