4proxy.nu is gone in the most literal sense: the name itself no longer exists in the domain system. The last page anyone saved from it dates to September 2017.
What it was
The Internet Archive's first working copy of 4proxy.nu is from August 2014 and it holds 7 days of captures in total.
Underneath it was PHProxy, the same free script the rest of the directory ran.
You can change your IP address to the secure Singapore IP address.
That is the site's own description, from the capture of 20 August 2014.
It was listed on workingproxysites.com, a directory of free web proxies, 12 years ago, and that listing counted 530 clicks through to it. The directory recorded it as Singapore.
When it stopped
The last capture that shows the proxy itself is from 12 September 2017 and the archive kept visiting until 20 March 2018.
By 20 March 2018 the same address answered with something else: the capture from that day is titled "The domain name 4proxy.nu is for sale | Undeveloped".
What the name does today
We checked 4proxy.nu on 10 September 2026 from our own server. The name does not resolve: there is no address behind it, so nothing can be served from it.
What to use instead
Use a list somebody keeps checking rather than a name that used to work. Our free proxy list is re-verified every few minutes, and an address that stops answering leaves it instead of sitting there for years. If you already have an address, the proxy checker will tell you whether it still relays anything.
The limits of free are the same everywhere, ours included: the addresses are shared, so the sites that care have seen them before, and there is no session to hold, so logins break part way through.
What this page cannot tell you
Why it stopped is not in the record. A dead name and an archive that runs out show that something ended, not the reason for it, and we will not put a reason in print that the record does not carry.
Our status check is one day from one vantage point, and a site that refuses requests from data centres would look the same as one that is switched off. We will check this page again by 1 January 2027.
