Protocols Carrying Address Information

Some IP application protocols, such as FTP and talk, pass address information over the network. This means that the application protocol will need to be modified to be multi-protocol, which generally means adding flexibility similar to what has to be done inside a network program. Exactly how to do this is outside the scope of this document, but an example is the approach used for FTP[7]. In general, the best solution to this problem is to change the application protocol to not send address information over the network, because this practice causes problems for many network/protocol translation devices.
