protocol is UDP
source IP is 17.10.1.127
source port is 137
destination IP is 17.255.255.255
destination port is 137
total length of packet is 78 bytes
type of service is 0x00
(10. `S=0x00' means the Type of Service field (divide by 4 to get the
Type of Service as used by ipchains))
IP ID = 4224
(11. `I=18' is the IP ID.)
F=0x0000
(12. `F=0x0000' is the 16-bit fragment offset plus flags. A value
starting with `0x4' or `0x5' means that the Don't Fragment bit is
set. `0x2' or `0x3' means the `More Fragments' bit is set; expect
more fragments after this. The rest of the number is the offset of
this fragment, divided by 8.)
time to live = T=32
13. `T=254' is the Time To Live of the packet. One is subtracted from
this value for every hop, and it usually starts at 15 or 255.
