Re: CIDR

In the December issue, there is a misprint in David A. Bandel's article “CIDR: A Prescription for Shortness of Address Space”. On page 26, under the CIDR heading, second paragraph, it states:

For a Class C address, this default subnet is 24 bytes long, so putting all ones in the first 24 bytes and zeroes in the rest, we have 255.255.255.0.

I think this should instead read 24 bits, rather than bytes, since each octet is composed of 8 bits, which gives 4 total bytes. Just wanted to bring this to your attention. Great article!

Mea culpa—you are 100% correct. Thank you for pointing out that little lapse of attention on my part. Guess I need to re-read everything thrice, because I read it twice and missed it both times. —dbandel@ix.netcom.com

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
