Welcome to the Improved CCNA Blog

For the last seven years, I’ve kept two blogs about CCNA content: The CCENT blog and CCNA blog. Keeping two blogs has had pros and cons, but I’ve always wondered if one blog would be better. Now’s the time! We’ve revamped the blogs into a single blog:

All CCNA Content Together! We merged the content from both blogs into the new CCNA blog.

New URL:  blog.certskills.com

Separate Per-Book Book Menus! The new blog menu begins with a multilevel menu for each book (ICND1 and ICND2.)

QA and Hands-on Menus Merged  The Hands-on and QA menus now show all types of blog posts from both original blogs.

Resubscription May be Required  If you had subscribed before, and don’t see subscription notices, just re-subscribe from any page in the blog.

I hope this new organization works well for you!
