Proxy glossary: key terms in plain language

Proxy types

Start here if you are deciding what to buy. Residential proxies use home connections, datacenter proxies use hosting facilities, and ISP proxies sit between the two. The comparison guides go deeper.

Definitions A to Z of the proxy terms we use

TermDefinition
ASNThe number that identifies an ISP's network, such as 7922 for Comcast. You can target an ASN in the username, for example -asn-7922.
AuthenticationHow a proxy verifies you may use it. Nefo credentials use a username and password, or an IP allowlist.
BandwidthThe volume of data that passes through your proxies, measured in gigabytes. On Nefo you buy prepaid bandwidth and consume it as traffic flows.
Datacenter proxyA proxy hosted in a data center. Fast and inexpensive, but its IP ranges are often recognizable as non-residential.
Exit IPThe final IP address a destination website sees for your request — the residential IP your proxy uses to reach the site.
GatewayThe entry point your client connects to, such as gw.nefo.net:9000. It is independent of the exit country, which you set with the country token.
Geo-targetingSelecting the geographic location of your proxy IP. Nefo residential proxies can be targeted by country, and in many countries by state, city or ISP.
HTTP(S) proxyA proxy that understands web requests. Convenient for browsers and HTTP clients, with HTTPS providing an encrypted connection to the destination.
IP addressA numerical label identifying a device on a network. Websites use it to infer approximate location and to distinguish visitors.
ISP proxyAn IP address issued by an internet service provider but hosted in a data center, combining ISP ownership with server-grade stability.
Non-expiring bandwidthPrepaid bandwidth that remains in your account until you use it, rather than resetting on a monthly cycle.
Proxy credentialThe host, port, username, and password you configure in a tool to send traffic through a proxy.
Residential proxyA proxy that routes traffic through an IP address assigned by an internet service provider to a real household device, so requests appear to come from a consumer connection.
Rotating sessionA configuration that assigns a new IP address on each request, useful for high-volume, independent lookups.
SOCKS5A proxy protocol that relays traffic at the connection level and supports both TCP and UDP, independent of the application protocol.
Sticky sessionA configuration that keeps the same IP address for a fixed duration, useful for multi-step tasks that should appear to come from one visitor.
UDPA connection type used by some apps and games. UDP works over SOCKS5 on Nefo's Pool 1.

Frequently asked questions

Residential proxies use IPs assigned to real households by ISPs, while datacenter proxies come from hosting facilities. Residential IPs blend in with normal consumer traffic for location-sensitive tasks. See the comparison.
