    Expanding IPv6 address using inet_pton

    hello every body,
    My name is roxy and i am from brazil.I want to expand IPv6 address using inet_pton().After that increment the address by 1 using C code.If my address is - 1234:12::ffff then after expand it will be 1234:0012:0000:0000:0000:0000:0000:ffff
    When I increment the address it will display - 1234:0012:0000:0000:0000:0000:0001:0000
    Whenever it will reaches ffff it just put 0x0000 and increment the next value by 1.
    I already done some code part(not the increment part).Please help me in this matter.
    Please find the attach docs.

    First I really doubt that you are using Linux because of the "conio.h", but well. Then why are you redefining the "struct in6_addr"?

    For expanding the IPV6 address, after some googling you should find that :

    Code:
    sprintf(buf, "%02x%02x:%02x%02x:%02x%02x:%02x%02x:%02x%02x:%02x%02x:%02x%02x:%02x%02x",
                     (int)ipv6.s6_addr[0], (int)ipv6.s6_addr[1],
                     (int)ipv6.s6_addr[2], (int)ipv6.s6_addr[3],
                     (int)ipv6.s6_addr[4], (int)ipv6.s6_addr[5],
                     (int)ipv6.s6_addr[6], (int)ipv6.s6_addr[7],
                     (int)ipv6.s6_addr[8], (int)ipv6.s6_addr[9],
                     (int)ipv6.s6_addr[10], (int)ipv6.s6_addr[11],
                     (int)ipv6.s6_addr[12], (int)ipv6.s6_addr[13],
                     (int)ipv6.s6_addr[14], (int)ipv6.s6_addr[15]);
    I guess that then for the incrementation you can use the in6_addr struct also, for example you start by incrementing the last part of the address, and if it gives 0 then you increment the next one...
