What is a Request for Comment (RFC)?
What will be an ideal response?
An RFC is a document prepared and distributed by any individual or group as a way to further networking, Internet, and computer communications. RFCs help ensure that network standards and conventions are provided so one network can talk to another. Every RFC is assigned a number to distinguish it from other RFCs and to provide a way to track it. Older RFCs are sometimes clarified, built upon, or replaced by newer ones. RFCs build cooperation in a community of equals and play a significant role in advancing network technologies.
