ipv4/25s and above

Dave,

I work for a smaller ISP in the Midwest with clients coast-to-coast. I deliver internet to about 2/3 rds of them over private ethernet circuits, the rest I deliver private addressed SIP service. Aside a handful of them who advertise their own /24 to me over BGP, the rest are exclusively smaller than that. /29's and /30's are the most common, with a peppering of /28's and /27's. My total IP space is about a /19.

Cheers!

    I am kind of curious as to the distribution of connections to smaller
    companies and other entities that need more than one ipv4 address, but
    don't run BGP. So, for as an ISP or infrastructure provider, what is
    the typical percentage nowadays of /32s /31s /30s... /25s of stuff
    that gets run "elsewhere"?

    Is there any correlation between the number of IPs a customer gets and
    the amount of bandwidth they buy?

    Obviously "retail", home use is /32s and there's an increasing amount
    of CGNAT, but I can't help but imagine there are thousands of folk
    running /27s and /29s for every /24 or /22 out there.

    I've been paying 15/month for a /29 for forever, but barely use it.
