Ip Address Flagged As Open Proxy
What is an open proxy and how do I configure my servers to …
An open proxy is a server that acts as a “middle-man” for requests from one server or network to another server or network and is accessible by any Internet user without restriction.
Open proxies do not filter, encrypt, or otherwise check what content is coming into servers. Because of this, they can allow malware to be downloaded and infect computers and can be used for the transmission of illegal content and spam.
Avoiding open proxiesSpamCop provides some good resources for fixing open proxies.

Hi Friends!
Apologies in advance if there is a better forum for this.
I just tried to sign up for an Instagram account from my computer, and when I went to verify the code they sent me, I got this:
The IP address you are using has been flagged as an open proxy. If you believe this to be incorrect, please visit
So my two questions are:
1. Does anyone know how to resolve this?
and
2. How can I determine if my computer is being used as an open proxy?

Open Internet Options (in Command or the Run type in “” without the quotes).
Open “Connections” tab. Open the “LAN settings” button. Under the “Proxy server” should be an unfilled field, IF not then you are using a proxy connection.
If there is a proxy connection, open the “Advanced” button and uncheck the unwanted connection. Then uncheck the previous field.
IF there is a proxy connection established, it maybe possible you have some sort of malware that altered your Windows’s setting. I strongly suggest you try to remove the malware or get help with this issue. Go here for the preparation work to get malware removed and follow the instructions from here: Then after following the guide, then post in here:
Hope this helps.

Oh forgot something browsers have builtin proxy connections such as Opera browser for example.
This could also show you are using a proxy server.

Nope just using Firefox.

OK check your public IP on this site (it should match the IP given to you from your ISP): If not then there is a proxy involved.

Oh check the Firefox browser to see if it has a proxy connection within itself, it can be there and it is not associated with the system connections.

Check your computer for malware, particularly Electricfish. It involves a 32-bit executable file implements a custom protocol that allows traffic to be funneled between a source and a destination IP address. Because the malware continuously attempts to reach to the source and the designation system, it is able to establish a funneling session. Electricfish malware is very stealthy because it can be configured with a proxy server or proxy username and password, a feature that allows it to connect to a system sitting inside of a proxy server. This gives cybercriminals the ability to bypass authentication to reach outside the network. In other words, using Electricfish, the Lazarus group is able to take over computers without their users knowing that they are compromised. What’s more, Electricfish constantly reinstalls itself even when it is removed. [/size][/size]

Open proxy – Wikipedia
An open proxy is a type of proxy server that is accessible by any Internet user.
Generally, a proxy server only allows users within a network group (i. e. a closed proxy) to store and forward Internet services such as DNS or web pages to reduce and control the bandwidth used by the group. With an open proxy, however, any user on the Internet is able to use this forwarding service.
An open proxy forwarding requests from and to anywhere on the Internet.
Advantages[edit]
An anonymous open proxy is useful to those looking for online anonymity and privacy, as it can help users hide their IP address from web servers since the server requests appear to originate from the proxy server. It makes it harder to reveal their identity and thereby helps preserve their perceived security while browsing the web or using other internet services. Real anonymity and extensive internet security might not be achieved by this measure alone as website operators can use client-side scripts to determine the browser’s real IP address and the open proxy may be keeping logs of all connections.
Most public VPNs work through open proxies.
Disadvantages[edit]
It is possible for a computer to run as an open proxy server without the computer’s owner knowing it. This can result from misconfiguration of proxy software running on the computer, or from infection with malware (viruses, trojans or worms) designed for this purpose. [1] If it is caused by malware, the infected computer is known as a zombie computer.
Testing for access from an open proxy[edit]
Because open proxies are often implicated in abuse, a number of methods have been developed to detect them and to refuse service to them. IRC networks with strict usage policies automatically test client systems for known types of open proxies. [2] Likewise, a mail server may be configured to automatically test mail senders for open proxies, using software such as proxycheck. [3]
Groups of IRC and electronic mail operators run DNSBLs publishing lists of the IP addresses of known open proxies, such as AHBL, CBL, NJABL (till 2013), and SORBS (since 2002).
