Code:
$ for i in $(cat infile) ; do echo "ibase=16; $i" | bc ; done | xargs

What do you get when you run it on your own sample?
I get:
Code:
$ awk '{for(i=1;i<=NF;i++)$i=sprintf("%0d","0x"$i)}1' infile
0 0 0 4 10 2 5 1 0 0 0 0 10 10 50 199 0 0 0 0 10 10 50 243 10 10 43 45 0 0 0 0 0 0 0 8 128 1 6 109 38 228 0 2 0 0 0 0
6 109 10 128 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

If using gawk, then try option --non-decimal-data
Code:
$ awk '{for(i=1;i<=NF;i++)$i=sprintf("%0d","0x"$i)}1' infile

Thanks Ygor, that solves the mystery. Another gawk quirk, it seems..
Code:
awk --posix

also seems to do the trick, perhaps for different reasons? It looks like gawk (as an extension) is interpreting these constants, while reading them, whereas I want them to be treated as simple strings and let printf do the conversion...

I have written the data into hexdata.log output as for one of the entries

Code:
0 0 0 4 235 20 192 65 0 0 0 0 10 20 40 99 10 10 34 24 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 152 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Need to be able to pull out words , these are actually IPs
5-8 -235.20.192.65
13-16 -10.20.40.99
16-20 - 10.10.34.24
29-33 - 0 ( C -Count )

So the output file reads as

Code:
245.20.192.65 10.20.40.99 10.10.34.24 c:0
