Features and recommendations
Spanish proxies are convenient for accessing local resources.
SOCKS4 is outdated and does not support DNS, so it's best to avoid it for modern tasks.
Make sure IPv6 is supported if the hosting uses it.
Many Spanish data centers limit speed with a large number of requests from a single IP.
It is recommended to set a connection timeout of 3-5 seconds to filter out slow proxies.
For parsing local sites, use residential addresses instead of proxy servers.
Pay attention to response time: stable proxies respond within 200-400 ms.
