Thanks for the advice, guys! I've released the next version of AsyncSocket, incorporating these changes. I'd probably vote for this as well. It's not the best approach in the specific case you mention (-acceptOnAddress:port:), but it's the best solution in general. Whichever I choose, I want to support both IPv4 and IPv6 addresses. I don't care about DNS names. But I will need to be able to verify that the developer did not pass a DNS name or an address of another computer to the method. And I need to end up with a sockaddr struct. You can just let bind do this for you. If you try to bind to an address that's not local, you'll get an error (AFAICT EADDRNOTAVAIL). I haven't had to deal with the extra difficulties you'll face, and you've probably already got this far, but here's what I use to go from NSString to sockaddr: struct sockaddr_in socketAddress; socketAddress.sin_family = AF_INET; socketAddress.sin_port = htons(fRemoteHostPort); inet_aton([fRemoteHostIPAddress cString], & (socketAddress.sin_addr)); memset(&(socketAddress.sin_zero), '\0', 8); // zero the rest of the struct If you want to work at the BSD level, I think that getaddrinfo <x- man-page://3/getaddrinfo> is the best choice. It supports both v4 and v6. By passing AI_NUMERICHOST, you can get it to just support the textual representation of numerical IP addresses, and never hit the wire.
