Students and readers of the Computer Networking: Principles, Protocols, and Practice ebook who want to stay up-to-date on the evolution of the networking technology should subscribe to the Internet Protocol Journal. The first issue of this journal was published 25 years ago. Initially distributed on paper, it is now mainly available as pdf files from https://ipj.dreamhosters.com/. Each issue contains very interesting tutorial articles that describe new protocols or discuss the evolution of networking technologies.

The last issue contains three interesting articles:

• a tutorial on the ALTO protocol that enables applications to obtain information about the current state of the network
• a discussion on the implications of randomizing MAC addresses in Wi-Fi or Ethernet networks
• a reflection on the main changes that have affected the Internet during the last 25 years
