Dear John,
I saw your emails for pointing out the bug. If you are working to fix it.
I figured out the problem.
I hope problem will be solved if you replace the following code of the function
char * ipv4_inet_ntop(char *destination)
{
memset(destination,NULL,sizeof(destination));
snprintf( destination ,IPV6_BUFFER_LENGTH,
"%03x:%03x:%03x:%03x:%03x:%03x:%03d.%03d.%03d.%03d" ,
str.ip6[0],str.ip6[1],str.ip6[2],str.ip6[3],str.ip6[4],str.ip6[5],
(((unsigned int )str.ip6[6]>>8) & 0xFF),
((unsigned int )str.ip6[6] & 0xFF),
(((unsigned int )str.ip6[7]>>8) & 0xFF),
((unsigned int )str.ip6[7] & 0xFF));
return destination;
}// end of ipv4_inet_ntop function
The new function code,
char * ipv4_inet_ntop(char *destination)
{
memset(destination,NULL,sizeof(destination));
snprintf( destination ,IPV6_BUFFER_LENGTH, "%d.%d.%d.%d" ,
(((unsigned int )str.ip6[6]>>8) & 0xFF),
((unsigned int )str.ip6[6] & 0xFF),
(((unsigned int )str.ip6[7]>>8) & 0xFF),
((unsigned int )str.ip6[7] & 0xFF));
return destination;
}// end of ipv4_inet_ntop function
I haven't run it, but I think it will be fixed. The problem is only this
function. Rest of the code base is work well. If you need more help. Feel free
to ask me.

Yup, that's what I meant :-) Best way to get stuff fixed is to fix it
yourself, right?

That would be most welcome! I'm branching off bazaar right now, I'll
dwell into the code as soon as its done. I'll post here with questions,
if I have nay.
Cheers.
