Hi,

I am using bind 9.2.1 and captured a query packet using tcpdump. In 
addition to QDCOUNT=1, it contains ARCOUNT=1. Two questions 1) is it 
legal? 2)why should a query packet contain AR records?

here is the packet in hex

     5313 0110 0001 0000 0000 0001 <- ARCOUNT
     0377 7777 0475 636c 6103 6564
     7500 000f 0001 0000 2908 0000
     0080 0000 00

Thanks,

rajeev
