Agents are an important supplement to any computer network. Use it to ensure that you get an anonymous, more secure private connection. Of course, there are some caveats, but, in most cases, proxies can provide these benefits and many more. There are also many types of agents, each with different functions, which may complicate the process of choosing the right type for your business. Fortunately, this article will help you by detailing the various available agents, their functions, and their use.
What is an agent?
The proxy is an intermediary between the user’s computer and the Internet. All web requests from the former are routed through the proxy, which assigns them a new IP address before establishing a connection with the target web server. At the same time, the agent also intercepts the content sent by the website. In short, they prevent direct communication between the user’s PC and the web server, which leads to the anonymous connection we previously implied.
The IP address identifies the computer in the network. They work more or less like human names, which means that the user’s network activity will be attached to these identifiers. It is worth noting that Internet Service Providers (ISPs) will keep logs of their customers based on IP addresses for a long time. This practice is especially likely to cause alarms at present, because network attacks have reached the highest level in history.
Actually, just The first six months of 2019, For example, more than 4 billion data leaks have been recorded. Forecasts indicate that this and other forms of cybercrime will increase in the future. Therefore, your data is not as secure as you think. In other words, using a proxy can help you minimize the risk of data leakage by ensuring that your ISP does not log your network activities. By doing so, the agent can promote privacy and security.
There are different types of agents, including:
- Residential agency
- Data Center Agent
- HTTP proxy
- Transparent proxy
- Reverse proxy
- Anonymous proxy
- High anonymity proxy
- Shared agent
- Private agent
- Rotating proxy
A residential proxy is an intermediary that routes web traffic through real users’ devices. It assigns them residential IP addresses, which are registered by the ISP and belong to the ISP. Therefore, web servers usually interpret web traffic as coming from real users, which means that residential proxies are rarely blocked. However, because residential agencies are expensive, they bring additional costs.
Residential agents are very suitable for the following applications:
- Crawl large websites, including buying sneakers
- Email monitoring to prevent phishing
- Accessing Restricted by region content
- Advertising verification
- Social media management
- Buy sports shoes agent
- Conduct market research
Data Center Agent
The data center agent is a virtual intermediary that exists in the cloud. They are created by powerful data center servers that generate multiple virtual IP addresses. Compared with residential agency, this kind of agency is cheaper and faster.
The data center agent is used to:
- Crawl small sites online, including buying sneakers
- Email monitoring
- Access geo-restricted content
- Solve the IP address ban
- Marketing and academic research
An HTTP agent It is a local intermediary. You can configure your computer or browser as an HTTP proxy. You also enter the IP address you intend to use as a proxy. From then on, any web requests generated by your browser will be routed through this proxy and sent to the target website before the IP address assigned to the HTTP proxy.
There are two types of HTTP proxy, namely HTTP client proxy and HTTP server proxy. The former was created when the computer was configured, and the latter appeared when the web server was configured.
HTTP proxy is used to:
- Content filtering
- Block the entire URL
- Allow or deny specific cookies
The shared proxy assigns the same IP address among multiple users. They are slow and take high security risks. However, their uses include:
- Access geo-blocked content
The dedicated agent assigns a unique IP address to each user. They enhance privacy, security and anonymity.
The transparent proxy delivers the content as is, without any modification. They are used in organizations where the administrator wants to restrict access to certain websites without obviously using a proxy.
The reverse proxy provides additional security for the web server. They are located at the end of the web server connected to the Internet, so they receive web requests on behalf of the server before allowing requests that they consider safe. In contrast, the other proxies listed here are forward proxies, they relay requests on behalf of the web client and are located on the web client.
The anonymous proxy hides the user’s real IP address, assigns a new IP address, and identifies itself as a proxy for the Web server.
High anonymity proxy
High anonymity proxies and anonymous proxies have similar functions, the only difference is that they do not identify themselves as agents.
As you know now, choosing a proxy depends on the purpose for which you intend to use it.
