Mobile proxy
A proxy exiting through a mobile carrier address, shared by many real handsets via carrier-grade NAT.
A mobile proxy routes traffic through an address assigned by a mobile network operator — the same kind of address a phone on 4G or 5G uses.
#Why they are the hardest to block
Mobile networks place large numbers of subscribers behind a small number of public addresses using carrier-grade NAT. A single mobile address may represent hundreds or thousands of genuine users at once. Blocking it means blocking all of them, so filtering systems are markedly more tolerant of mobile ranges.
#The cost of that tolerance
- The most expensive category, by a wide margin.
- Higher and more variable latency than any other type.
- Addresses rotate on the carrier’s schedule, not necessarily yours.
- Smaller pools, since each address is a real SIM on a real network.
#When it is worth it
Mobile-only surfaces, and targets whose anti-bot systems have defeated every cheaper category. It is a last resort by design, not a default.
