Meh. What should be fixed is that connect() should receive a name instead of an IP address. Having an application deal directly with the IP address should be the exception rather than the rule. Then, deal with the TTL issues once in the standard libraries instead of repeatedly in every single application.
In theory, that'd even make the app code protocol agnostic so that it doesn't have to be rewritten yet again for IPv12.
While I agree with the principle of what you are trying to say, I would argue that it should be dealt with in getnameinfo() / getaddrinfo() and not connect().
It is perfectly reasonable for connect() to deal with an address structure.
Yes, well, that's why we're still using a layer 4 protocol (TCP) that can't dynamically rebind to the protocol level below (IP). God help us when folks start overriding the ethernet MAC address to force machines to keep the same IPv6 address that's been hardcoded somewhere or is otherwise too much trouble to change.
