More proxy IPs are not more server capacity

A datacenter proxy list counts addresses. It does not count physical servers, reserved bandwidth or simultaneous connections. This distinction matters when a larger package fails to make a collection job finish faster.

Separate the resources

One server can use multiple public IP addresses. Its proxy software chooses an available source address for an outgoing connection. Several customers may use the same hardware while receiving different addresses.

A dedicated IP allocation reserves those addresses for you. It does not automatically reserve the machine or its network link. Similarly, rotating to another exit does not prove that traffic moved to a different server.

Suppose a hypothetical workload has enough addresses but repeatedly reaches its connection allowance. Adding addresses without increasing that allowance leaves the limit unchanged. If the bottleneck is bandwidth, a larger list can still share the same constrained link.

Measure the job you need to complete

Record three things during a representative run:

• How many requested pages produce usable content.
• How long the job takes at the intended number of concurrent connections.
• Which resource limit or failure appears as load increases.

A fast challenge page is not a successful collection result. A response from an IP-check page establishes basic connectivity, but does not establish access to the intended destination.

Check network variety separately

Several addresses can belong to the same range or ASN. If a destination restricts that network, switching between those addresses may not change the response. Address count and network variety answer different questions.

The purchasing decision follows the observed constraint. A small fixed list may be enough for a stable outbound address. A larger allocation may help when distinct addresses are actually required. More throughput needs suitable server capacity, connectivity and plan limits.
