> don't use an IP range classified as "consumer" (known dynamic IP DSL/cable ranges)

How can you tell if the IP you use is or has been in one of those ranges?

I think "consumer" is being contrasted with a business contract offering static ip.

You should know because it is currently blocked - found by using mxtoolbox.com for example.

Or, suspect it will be because the ip to your residence is not a designated static ip. (In practice it may be ipv6 and never changes but applying a PTR to the ip requires assistance from the ISP and it would likely be outside of the contract.)
