Proxy server
A proxy server, also known as a "proxy" or "applicationlevel gateway", is a computer that acts as a gateway between a local network (for example, all the computers at one company or in one building) and a largerscale network such as the internet. Proxy servers provide increased performance and security. In some cases, they monitor employees' use of outside resources. A proxy server works by intercepting connections between sender and receiver. All incoming data enters through one port and is forwarded to the rest of the network via another port. By blocking direct access between two networks, proxy servers make it much more difficult for hackers to get internal addresses and details of a private network. Some proxy servers are a group of applications or servers that block common internet services. For example, an HTTP proxy intercepts web access, and an SMTP proxy intercepts email. A proxy server uses a network addressing scheme to present one organizationwide IP address to the internet. The server funnels all user requests to the internet and returns responses to the appropriate users. In addition to restricting access from outside, this mechanism can prevent inside users from reaching specific internet resources (for example, certain websites). A proxy server can also be one of the components of a firewall. Proxy browser is one free proxy well known on search engines worldwide. Proxies may also cache web pages. Each time an internal user requests a URL from outside, a temporary copy is stored locally. The next time an internal user requests the same URL, the proxy can serve the local copy instead of retrieving the original across the network, improving performance. Do not confuse a proxy server with a NAT (Network Address Translation) device. A proxy server connects to, responds to, and receives traffic from the internet, acting on behalf of the client computer, while a NAT device transparently changes the origination address of traffic coming through it before passing it to the internet. For those who understand the OSI (Open System Interconnection) model of networking, the technical difference between a proxy and a NAT is that the proxy server works on the transport layer (layer 4) or higher of the OSI model, whereas a NAT works on the network layer (layer 3). You may not know it (and once you do not know it, it may not bother you), but every time you reach out to a website or connect with anyone online, your online connection gives your computer "address" to the site/person you're connecting with.
Why? So that you the other end knows how to send information (a Web page, email, etc.) back to your computer...to you. That address is your public IP address. IP stands for Internet Protocol. Want to see yours right now? Just go here to our home page and it will be there. Without an IP address, you wouldn't be able to do any Internet/online activity and others online wouldn't be able to reach you. It is how you connect to the world.
Unblockwebsites is also the best free proxy to use to hide your ip and id. ou can thank your Internet Service Provider (AT&T, Comcast, Verizon, etc.) for your IP address at home, as well as for your Internet connection. Your smart device also uses an IP address when you're browsing the web or using an app. Most people are completely happy with how all of that works. But there are few realities about public IP addresses that does bother some people:
Your IP address identifies where you are in the world, sometimes to the street level. It can be used by websites to block you from accessing their content. It ultimately ties your name and home address to your IP address, because someone is paying for an Internet connection at a specific location.
But there are a few ways you can get around those realities, and one them is to use a proxy service or proxy server (people simply say "proxy.")
