Yup, still listed as 22.214.171.124/14
As long as you're there, I've also got the adjoining 23.19 blocked. Server farm, apparently.
And, in the other direction: if 126.96.36.199/14 is still Comcast Business, they're probably expendable as well.
Come to think of it, I don't see much of anything in 23 except for a couple of Canadian IPs. Most of the range is-- or was until recently-- unassigned, so I'd expect a lot of filling-in over the next couple of years.
