{section: Note for constants}
Don't forget constants that should be adjusted!

Original implementation was just re-invention of inet_ntop()/inet_ntoa(). So, I replaced to new implementation that calls inet_ntop() twice. (with AF_INET and AF_INET6)
+{subsection: struct hostent}
+
+I Initially only looked at struct sockaddr_in. I wrote class ipaddr for replacement. However, it is only half of the world. I should devise IPv6 compliant structure for struct hostent and make it obsolete. I think it would make more sense if we have class ipaddr and class MyString instead of sockaddr* and char*. Write here some design possibilities!

+{code}
+// from MSDN
+typedef struct hostent {
+ char FAR *h_name;
+ char FAR FAR **h_aliases;
+ short h_addrtype;
+ short h_length;
+ char FAR FAR **h_addr_list;
+}
+
+typedef struct addrinfo {
+ int ai_flags;
+ int ai_family;
+ int ai_socktype;

{subsection: get_full_hostname}
+my_ip_addr, my_hostname, my_full_hostname() and get_full_hostname() are now obsolete. Now, implementing ipv6_hostname.{h/cpp}.
+
It uses gethostbyname() which has been obsoleted. It should call getaddrinfo() instead. The function has about 150-200 lines of code. At the end of function, it tail-calls get_full_hostname_from_hostent(). struct hostent is also deprecated structure.
It requires overhaul from interface to implementation.
