The decline we flagged last issue played out and is now flattening. Residential Proxy IP shed 7.1 million IPs since July 7, but the daily give-back has slowed from roughly 420,000 a day at its steepest in mid-July to under 70,000 a day this week, and the pool even posted two up-days on July 24 and 25. IPv4 residential grew 1.2% across the same stretch; every IP the window lost was IPv6.
Database at a glance
| Metric | Jul 7 | Aug 3 | Δ |
|---|---|---|---|
| Residential proxy IPs (90d) | 142,467,330 | 135,341,116 | -7,126,214 (-5.0%) |
| Mobile proxy IPs (90d) | 3,262,853 | 3,803,322 | +540,469 (+16.6%) |
| Datacenter proxy IPs (90d) | 1,203,107 | 1,175,839 | -27,268 (-2.3%) |
| Active providers contributing IPs (90d) | 117 | 126 | +9 |

The 126 active providers break down as 124 residential, 3 mobile, and 7 datacenter, with some contributing across categories.
Where the residential decline landed
Residential IPv4 went from 66.2 million to 67.0 million, up 785,000. Residential IPv6 went from 76.3 million to 68.3 million, down 7.9 million, or 10.4%. The net -5.0% is those two numbers pulling against each other.
NetNut went dark in early July, so the addresses that were only ever visible through that one network have been aging out of the 90-day window on schedule ever since, and they skewed heavily IPv6. The addresses that were also being resold through other networks never left. The steepest week was July 9 to 16, and the last four days have run at roughly a sixth of that rate.
Two practical reads. First, if you score residential-proxy risk on IPv4, this event cost you nothing and the pool is still growing. Second, the churn floor under IPv6 is real and it cuts both ways: v6 additions arrive fast and v6 losses clear fast.
Inside the residential pool
Structure held. As of August 3, 46.1% of residential IPs were seen exactly once (27.0% of IPv4, 64.8% of IPv6) and 39.5% appeared under more than one provider (62.9% of IPv4, 16.6% of IPv6). The one number that moved is IPv6 multi-provider overlap, down from 19.6% to 16.6%, and it moved for the reason above: the addresses that washed out were disproportionately the widely-resold v6 ranges. IPv4 lifetime got a little stickier, median up to 5.6 days with the 75th percentile at 40.8 days. IPv6 is still a flat one day at both.
What changed behind the scenes
- Deduplicated a shared upstream. Two separately-branded services in our catalog turned out to be reselling a single upstream network. We collapsed them into one provider entry rather than double-counting the same fleet under two names, which keeps the provider-overlap figures above honest.
- Capture reliability hardening. Ongoing work to keep high-volume residential feeds reporting steadily, so window-over-window movement reflects the networks and not our collection.
