What Instagram proxies are and how they work
An Instagram proxy is an intermediary IP address that sits between your browser or automation tool and Instagram's servers. Instead of Instagram seeing your own connection, it sees the proxy's address, location and network type. This matters because Instagram builds a trust profile around each account that ties together the IP, device fingerprint, timezone and behaviour.
When you route an account through a stable proxy, Instagram associates that account with a consistent location and network. That does not make you a different person in Instagram's eyes, though: the account itself, its history and how you use it all still count, and the same rules apply.
Budget Proxies gives you control over the protocol (HTTPS or SOCKS5), the authentication method and whether the session rotates or stays sticky. That control means an account you look after can stay on one steady connection instead of a new shared address on every visit.
