These are the IPs I managed to map, not the full size of any provider’s network.
After combining the lists for 711, IP Royal and Proxy Seller, I had 964,797 unique IP addresses. One is IPv6; the rest are IPv4.
The US accounts for 510,522 addresses, Brazil 267,707, the UK 113,239 and Canada 71,980. The remaining 1,349 are spread across other countries.
Three providers
I counted 625,634 IPs for 711, 98,858 for IP Royal and 273,246 for Proxy Seller. The provider totals overlap, so they add up to more than the overall count.
Where they cross
711 and IP Royal share 27,434 exact IPs. IP Royal shares 5,505 with Proxy Seller, while 711 shares 1,966 with Proxy Seller. 1,964 addresses appear in all three lists.
The map
Every unique IP is on the map. I grouped them into 9,390 location cells to keep it usable. Toggle a provider, zoom in and hover for counts. Split markers show IPs listed by two providers; three colour markers show those listed by all three.
Brazil stood out
Turn on Proxy Seller and Brazil lights up orange. 267,696 of its 273,246 IPs, just under 98%, geolocate there.
That surprised me because, when mapping the data, I specified the USA, Canada and UK only. More than 99.98% of the IPs returned for each of those countries geolocate to Brazil in DB-IP City Lite. I checked the IPtoASN data too: it marks 264,073 Proxy Seller addresses with a BR country code.
The networks behind the addresses
