| 13 | 4 | Laurent GUERBY | sileht: dig sur bind permets de recuperer le vrai hostname de la machine interrogée : |
| 14 | 4 | Laurent GUERBY | dig @sileht.net hostname.bind txt ch |

| 19 | 7 | Laurent GUERBY | FYI: here's a pcap filter that will match only UDP DNS ANY queries: |
| 20 | 7 | Laurent GUERBY | |
| 21 | 7 | Laurent GUERBY | udp and dst port 53 and udp[10]&0xf8=0 and udp[12:4]=65536 and udp[16:4]=0 and udp[udp[4:2]-3]=255 |
| 22 | 7 | Laurent GUERBY | |
| 23 | 7 | Laurent GUERBY | It only works for IPv4 (that's a pcap limitation). |
