Proxies in Germany
The busiest European direction. Hosting is dense, latency across the continent is low, and the price per address sits at the bottom of the European range.
Why it became the default in Europe
The country holds one of the largest concentrations of datacenter capacity in Europe, and competition keeps prices down.
For jobs that touch several European markets in one run, this is usually the cheapest place to sit.
Ranges are well known
The same density that makes it cheap makes it familiar to the platforms. German hosting ranges appear in filter lists more often than most.
Ask the vendor how many distinct subnets are in the set while you can still walk away.
Language and results
Search results served to a German address come back in German by default. If you compare against another market, fix the language explicitly.
A working pool
Thirty addresses across at least six ranges covers a daily run against several European retailers.
