# How can I tell whether my proxy is sticky or rotating?

Standard proxy format: `Domain:Port:User:Password`

## Rotating residential proxy

A rotating proxy assigns a new IP on each request.

Example: `basic.killerproxies.com:31112:fmuomw9b4tywj624zntiuz57hrcfwm:S2n9fLOlB9KXmyIB_country-UnitedArabEmirates`

## Sticky proxy

A sticky proxy includes a session value in the credentials.

Example: `basic.killerproxies.com:31112:fmuomw9b4tywj624zntiuz57hrcfwm:S2n9fLOlB9KXmyIB_country-UnitedArabEmirates_session-e2m0d86`

The `session-...` part indicates session persistence.

## ISP proxy format

ISP proxies use a direct IP format.

Example: `149.120.186.72:6725:MVWY58511:LPUVW015`
