Choose the network and session behavior your task requires, then compare the full purchase cost. A proxy category alone does not establish speed, successful access or how long an address stays available.
Start with the requirement
- Hosting-network addresses are acceptable: compare datacenter offers, including shared versus dedicated IPs, traffic allowance and rental period. Oxylabs, for example, distinguishes shared and dedicated datacenter products; their purchase conditions differ. Datacenter product scope: oxylabs.io/products/datacenter-proxies.
- A consumer-ISP pool is required: compare residential products and their targeting controls. Check what happens when a peer disconnects. In Oxylabs' residential session model, a normal session can move to another exit when its peer becomes unavailable. Residential session documentation: developers.oxylabs.io/products/proxies/residential-proxie….
- You need an allocated address for a longer workflow: compare the exact ISP/static offer, its rental term and replacement conditions. Oxylabs describes its ISP product as ISP-registered addresses hosted in datacenters. That product description does not guarantee uninterrupted availability or acceptance by your target. ISP product scope: oxylabs.io/products/isp-proxies.
- A cellular-network exit is part of the test: compare mobile products and confirm any required country or carrier. Use our mobile versus residential comparison to inspect product-specific network and session restrictions.
These are selection questions, not a ranking of proxy types. Shared public addresses can receive restrictions because of another user's activity; the IETF's address-sharing analysis explains why a carrier address does not confer immunity from blocking.

Compare three separate lifetimes
A paid rental or traffic balance, a configured sticky session and an established network connection can all end at different times. A long subscription does not reserve one residential peer for that whole period. An active application session does not prove its public exit stayed the same.
Decide whether your workflow can accept a replacement IP after failure. If it cannot, require a documented failure mode that stops instead of silently switching. Read the provider's session controls and keep the application's session state separate from the proxy-session identifier.
Work out the purchase before choosing a unit price
Use the price calculator with the amount and billing period you actually need. Check minimum order or wallet funding, how many GB or IPs the purchase buys, renewal, overage and the unused-traffic rule for that plan. Read the reviewed purchasing conditions on the provider record; an advertised nonexpiring PAYG balance does not establish monthly rollover.
For an intermittent task, compare PAYG retention and inactivity terms. For evaluation, compare trial eligibility and starter offers; a paid starter pack, requested business trial and refund policy are different offers.
Validate the shortlist
Before a large purchase, define the permitted target, required output, tolerable failures, session continuity and cost limit. Record outcomes for that workload if you perform a trial. This guide supplies source-based selection criteria; it contains no provider performance test or universal success-rate threshold.
