IPv6 proxy ops
IPv6 vs IPv4 Proxies: Why /64 Ranges Change the Game
Compare IPv6 and IPv4 proxy setups for scale, rotation, cost, and detection — and when a /64 subnet beats rotating residential IPv4.
Part of our IPv6 proxy management guide series.
Most proxy providers sell scarce IPv4 addresses at a premium. If you control a VPS with a global /64 IPv6 range, you effectively have billions of outbound addresses — one per connection or one per proxy port.
Scale without address exhaustion
A single /64 gives you 2^64 addresses. Even using a tiny fraction, you can run thousands of simultaneous proxies without NAT contention or provider IP recycling drama.
Rotation models
With MeshProx you can run:
- Static — one fixed IPv6 per proxy port (great for allowlists)
- Rotating — new IPv6 per client request
- Sticky — same IPv6 per session for N minutes
When IPv4 still matters
Some targets are IPv4-only. MeshProx agents prefer IPv6 egress but fall back to IPv4 when the destination has no AAAA record. For pure IPv6 targets (many modern CDNs), your exit IP is unmistakably from your subnet.
Bottom line
If you already pay for VPSes with IPv6, you're sitting on unused inventory. MeshProx turns that into a managed proxy fleet in minutes.
