Let’s hand write DNS messages | James Routley
In this post, we’ll explore the Domain Name Service (DNS) binary message format, and we’ll write one by hand. This is deeper than you need to use DNS, but I think it’s fun and educational to see how these things work under the hood.

Hypertext Transfer Protocol Version 2 (HTTP/2)
This specification describes an optimized expression of the semantics of the Hypertext Transfer Protocol (HTTP), referred to as HTTP version 2 (HTTP/2). HTTP/2 enables a more efficient use of network resources and a reduced perception of latency by introducing header field compression and allowing multiple concurrent exchanges on the same connection. It also introduces unsolicited push of representations from servers to clients. This specification is an alternative to, but does not o...

Introduction to Networking: Part 1, The Basics - Scott's Weblog - The weblog of an IT pro specializing in cloud computing, virtualization, and networking, all with an open source view
A router is a device that operates at OSI layer 3. Because network protocols exist at layer 3, routers are generally protocol specific. I’ve limited the discussion here to TCP/IP, but routers exist for other network protocols as well. A key difference between bridges/switches and routers is that routers actually modify the packets moving across them, typically by changing the layer 2 addresses in the packet and by decrementing the Time To Live (TTL) counter. The TTL counter is a fiel...
