Plan residential proxy traffic before buyingResidential proxies are billed by traffic. A country, payment coin and session mode are separate choices; changing the coin does not change the network you receive.Mobile proxy traffic or a dedicated device?A shared mobile pool and a dedicated mobile device solve different problems. Their billing, control and delivery steps should not be treated as interchangeable.How to order ISP static proxiesISP proxies provide dedicated static addresses for a fixed term. The main decision is the set of addresses and how long to retain them, rather than a traffic package.Buy datacenter proxies with the right capacityDatacenter proxies are dedicated server IPs. Their suitability depends on address count, traffic allowance and the destinations you intend to reach.Check proxy country availability before orderingA country in a search phrase describes the desired exit location. It does not reserve an address or guarantee stock.City targeting and fallback rules for proxiesCity targeting is more specific than country targeting and can reduce the number of usable exits. Treat a selected city as an availability request.ASN, ISP and carrier targeting: what changes?An ASN identifies a network operator, an ISP describes a provider category, and a mobile carrier is the radio network behind a mobile exit. These terms are not interchangeable.4G versus 5G mobile proxiesThe label 4G or 5G describes the connection technology of the mobile network, not a guaranteed speed for every request.ISP or datacenter static proxies: a buying comparisonBoth products provide dedicated static IPs, but the origin of an ISP address differs from a datacenter address. Choose based on the target and traffic model.Renew static proxies: request, confirmation and IP continuityRenewal requires a request and manual confirmation. Check the expiry date, quoted cost and whether the assigned addresses can be retained before the current term ends.Calculate volume discounts on static IP ordersA lower per-IP rate at a quantity threshold can change the total, but extra addresses still cost money. Calculate the complete order rather than buying solely to reach a discount.What happens between a proxy order and delivery?Proxy Cyber uses manual payment review and manual assignment for services that need dedicated resources. An order can be accepted before its credentials are ready.How manual wallet top-up confirmation worksA crypto transfer does not become spendable wallet balance merely because it was broadcast. The administrator must match and approve the payment.Choose the correct blockchain network for a proxy top-upThe same token and similar-looking addresses can exist on several blockchains. The transfer network must match the payment request exactly; the address format alone does not confirm compatibility.Proxy password or IP whitelist: which access method?Password authentication and IP whitelisting both control who can use a proxy gateway, but they fit different network environments.Give each client a proxy sub-user and traffic limitA sub-user separates one client's credentials and usage from the main gateway account. It is useful when several tools or teams share a purchased traffic balance.Export proxy credentials in the format your tool expectsThe same assigned proxy can be represented as host:port:user:pass, user:pass@host:port, a URL or CSV. A different text format does not create a new IP.What to do when a proxy order is delayedManual verification or a location-specific assignment can take longer than a simple balance update. The order record is the source of truth for the current stage.Choosing a proxy exit in Türkiye: network, city and verificationA Turkish exit is a location requirement, not a single product. Compare the network, session behavior and availability before ordering; an Istanbul request needs a separate city check.SOCKS5 or HTTP(S) proxy: how to choose and test the protocolProtocol names describe how a client connects to a proxy. They do not determine whether an IP is residential, mobile, ISP or datacenter, nor do they guarantee anonymity or speed.How to choose an IPv4 proxy without confusing the address and the serviceBuying an IPv4 proxy means purchasing access through a proxy endpoint, not ownership of a raw IPv4 address. Check whether the exit is shared or dedicated and how long it remains assigned.One proxy or a bulk order: plan quantity, term and total costA list of proxies, one dedicated address and a traffic pool are different purchases. Work backward from concurrent tasks and transfer volume instead of buying a large number of IPs from a keyword alone.
