Hello, I am no developer, please be patient
Enterprises have to make sure, that their business applications are IPv6 capable, this is dependent of the coding language. For that the code MUST use ip address family independed functions.
Good news: There are about 10 pitfalls and there will no new ones to come in the future.
IPv4-only-functions:
- INADDR_ addr_in
- F_INET
- gethostbyname
- gethostbyaddr
- inet_addr inet_ntoa
- Inet4Address
- inet_aton
- gethostbyname_ex
- 0.0.0.0
- 127.0.0.1
- 255.255.255.255
The last three are only common examples of IPv4 addresses (may be a regular expression, which find all IPv4 addresses is better)
For all the above IPv4-only-function is an ip address independent function available e.g. getaddrinfo instead of gethostbyname.
Every developer would benefit from using those ip address family independent functions. Some are releated to all languages (e.g. usage of ipv4 addresses), some others are more common in specific languages (e.g. gethostbyname in C/C++).
Please don’t hesitate to ask me, if you need any information.
