Response for IP Record Route Option is a question about a concrete network protocol (the TCP/IP family). Are such questions on-topic here?
If the question was about the implementation of the protocol in a particular operating system, it would be clearly off-topic. For example, if the question was about the
traceroute utility, I'd close it without hesitation. Conversely, if the question was about network modeling, or about the design of network protocols, it would be squarely on-topic. This is an intermediate case. What do we want to do about it?
