PNRP the New DNS – Peer Name Resolution Protocol

PNRP – The Peer Name Resolution Protocol is new protocol made by Microsoft which is one of the first technology that will change the way we think about naming resolution in computer networking and possibly be the next DNS – Domain Name System like technology. PNRP is the new DNS but there are so much differences between them that it deserves an article on this blog.

Just to remind, is few simple words, DNS is a technology that enables us to type the domain name in the browser and leaves to Domain Name System to translate the domain name to IP address of the server where the web page is published.

As we are stepping forward to IPv6 implementation in the whole world in next years, there are technologies and future services that will not function at their best using DNS. In this case Microsoft was one of the first to develop a new technology, decentralized technology that will rely on neighbor computer for the name resolution and completely rely on IPv6 addressing. The Per Name Resolution protocol was the answer.

In case of DNS, it depends on a hierarchical structure of naming, while PNRP depends on peer systems in order to resolve the computer system’s location. Mainly, PNRP is a referral system that operates lookups on the basis of data it is familiar with.

PNRP - Peer Name Resolution ProtocolHere is a simple example, if you require to search Computer 1 and you are close to Computers 2 and 3, it is important for your system to know whether Computer 2 knows Computer 1 or not. If the response of Computer 2 is positive, only then a a link to Computer 1 is provided to you. If the reply is in negative, then the system asks Computer 3 whether it knows Computer 1 and the same method is used with Computer 2. If none of the computers knows Computer 1, then the request is sent to other computers close to the system till it successfully finds the one that is familiar with Computer 1.

There are number of ways in which PNRP is different from the DNS service:
