Print hex Ip address in decimal format inside awk script
Hi to all,

May someone help me with the following.

The awk script below is part of a bigger awk script, and this part attempts to print an Ip address that is in hex format in decimal format. I'm trying with following code but
I'm getting 0.0.0.0 and the correct answer is 192.168.140.100

Code:
echo "d djjd:C0 A8 8C 64 00 00 00" | 
awk '{a=gensub(/.+:(..) (..) (..) (..).+/,"\\1 \\2 \\3 \\4","g");split(a,b);printf("%d.%d.%d.%d","0x"b[1],"0x"b[2],"0x"b[3],"0x"b[4])}'
0.0.0.0

Thanks in advance,
