@Alan : 我认为子网划分在网络中扮演着至关重要的角色,但往往被低估。通过子网掩码和AND运算,我们可以快速判断两个IP地址是否位于同一网络,从而决定是否需要通过路由器进行通信。这种方法非常高效,计算机每秒都会进行多次这样的运算。路由表也是基于这种运算构建的,通过最长匹配原则,我们可以找到最合适的路由。在教学过程中,我发现有些人能够理解这种数学运算的精妙之处,而有些人则只是死记硬背子网掩码的含义。理解子网划分的原理,可以帮助我们更好地理解互联网的运作方式。

Deep Dive

Chapters
This chapter explores the elegance of subnetting in networking, explaining how subnet masks and simple math operations enable efficient routing of traffic across the internet. It highlights how this seemingly simple concept scales to support the massive size of the internet.
  • Subnetting uses subnet masks and AND operations to determine network proximity.
  • Efficient routing is achieved through longest match routing based on subnet masks.
  • Understanding the underlying math simplifies networking concepts.

Shownotes Transcript

We appreciate the elegance of subnets as well as the power of custom benchmarking, Xboxes will support large amounts of external storage, why it’s not looking great for bcachefs, malware and remote desktops, and our thoughts on Fortigate network gear.
