Answer 2

Just to clarify, you're looking to parse a string representation of an IP Address, to an IPAddress object?

(That's my understanding of this article explaining INET_NTOA)

In that case ,it's System.Net.IPAddress.Parse("127.0.0.1"), and you can use the .ToString() off an IPAddress to get the string rep back out.

Answer 3

The IPAddress class has static methods:

HostToNetworkOrder
NetworkToHostOrder

With various overloads.

Answer 4

To make NTOA compatible with MySQL i had to do a Endian conversion

byte[] ip = BitConverter.GetBytes(ipInt);
Array.Reverse(ip);

IPAddress = new IPAddress(BitConverter.ToUInt32(ip,0))
