Which proxy terms are used on this site?
- Residential IP
An IP address assigned by an internet provider to a home connection. Websites see it as an ordinary household visitor.
- Exit IP
The address your request leaves the proxy network from; the one the target website sees.
- Gateway
The single host you connect to (
gw.metroproxies.com), which forwards each request to an exit IP matching your username segments.- City targeting
Asking the gateway for an exit IP in a named city with the
city-segment. Availability depends on the devices online there.- Rotating session
Each new connection gets an exit IP from the pool, usually a different one.
- Sticky session
The same exit IP for a set time, chosen with
session-andttl-segments; here up to 30 minutes, set per session with the ttl parameter; the IP can change earlier.- ASN (autonomous system number)
The number under which a network, such as an internet provider, announces its IP ranges. AS7922 is Comcast; AS20115 is Charter (Spectrum).
- Sub-user
A separate set of proxy credentials under your account, with its own traffic cap, for one project or client.
- SOCKS5
A proxy protocol that carries any TCP traffic. Browsers do not send a username to SOCKS5 proxies, so use HTTP in browsers.
