Convert byte[] to string and back again

I have an application that is storing the IP Addresses of requests in the database as a varbinary(16) in a manner described here: Byte Array Size for a IPv6 IP Address.

I need to pass the IP Address from one server to another. For that reason, I cannot just rely on the Request object. My question is, if I have the IP Address as a byte[], how do I encode it as a string and then decode it as a byte[] again? I always get confused with the ASCII, UTF8, Unicode, etc. encodings.

Thank you so much!

For a slightly more user-friendly string representation, you can use Base64

str = System.Convert.ToBase64String(bytes);
bytes = System.Convert.FromBase64String(str);

var ipString = (new IPAddress(myBytes)).ToString()

then at the other end

var addressBytes = IPAddress.Parse(ipString).GetAddressBytes();
