Talk:CIDR notation

In IPv4 & IPv6 articles

It's in them to some extent; it is the standard for IPv6 and subnet masks are deprecated in IPv4.

I've changed "subnet mask" to "network prefix".

Many routers do this comparison with hardware assistance, and, in some cases, with ternary rather than binary masks. Howard C. Berkowitz 00:44, 27 October 2009 (UTC)

I'm never sure whether to edit an existing article like IPv4, or just write a new one when I need a quick explanation of a topic like CIDR notation. The need for a short explanation came up in an article on an email authentication method (SPF). In this case, an entire article on IPv4, or even CIDR, would be too much. --David MacQuigg 12:07, 27 October 2009 (UTC)
