The Internet is based on information exchange. It is performed according to the established rules. These are the network protocols followed by end-users, web servers, paid and free supreme proxies granted by Dexodata. The client chooses whether to buy proxy HTTPS of residential, datacenter or mobile type.

The protocols consist of different levels. They can be compatible with others and work on the common principle. Client sends a request to the server to launch a website or web application. The message must be correctly encoded, must be sent to the right address, and the client's IP must be off the "black list". If you buy residential and mobile proxies in Canada, Singapore etc. they should be provided by a trusted platform.

If the conditions pass the checklist, the server recognizes the request and responds to it with text, media files, etc. 

Network protocol: what is it?

There are hundreds of protocols and about ten categories to which they belong. In 1982, the OSI (Open Systems Interconnection) model appeared as a general classifier. However, forty years later, it has become obsolete. The network rules apply several layers of the model at once: internetwork, channel, transport, and application.

This can be seen in the TCP/IP example, on which HTTP is based. The second popular protocol - UDP - serves as the base for SOCKS5.

These both are available in our data collection and management infrastructure. For geo targeted proxies is enough to change the connection port, in addition to the protocol changing ability.


TCP/IP: how it works and what can do


TCP/IP bases on fourth structural level and consists of two components:

  • IP is responsible for routing information and keeping track, which address the message goes to.
  • TCP as a transport protocol ensures that the message is delivered intact.

When one is eager to buy HTTPS proxy list and to run it, IP indicates the address and adds a header to the digital "package". Addresses have two formats: 32 bits (IPv4) and 128 bits (IPv6). 

TCP breaks the file into packets, numbers them and checks for errors at the beginning and at the transfer’s end. The assignment of the communication port also lies with TCP. The end device, according to the rules, collects the packets back into a file. Any paid or free supreme proxy server in the Netherlands or Vietnam make sites repeat the procedure twice.


Is HTTP protocol the Internet basis?


HTTP (HyperText Transfer Protocol) refers to pages placed together by links. Every click opens an internal section or leads to another page, e.g. when you buy residential and mobile proxies. 

HTTP has been evolving for forty years. It has come the way from processing only HTML documents to transferring any web data, incl. free supreme proxies.

HTTP uses the TCP/IP stack. IP is the header and destination address. It describes the data and adds information useful for a successful transfer. E.g., private information about the sender's device or message handling options. Trusted proxy websites keep headers secured, unlike free proxy lists. 

The TCP segment consists of the message itself with application information:

  • Checksum to verify the file
  • Source and destination port numbers
  • Window size
  • Title length, etc.


What is HTTPS?


HTTP uses no encryption. Even HTTP geo-targeted proxies in Egypt, Australia or Italy proceed the same. They form a tunnel to move requests and responses through, but do not hide the packets’ content. So what is inside comes available for interception and reading.

How to buy residential and mobile proxies both HTTP and HTTPS proxy list compatible?

 HTTPS is an updated encrypted version of HTTP, accompanying it, just as satellite follows the Earth   

The flaw is fixed by HTTPS adding an SSL certificate to the broadcast. This is an individual decryption key. Only the client and the server know it, and with a new connection, the cipher changes. That’s why it is safe to buy proxy HTTPS for social media.

HTTPS stacks other protocols. This is not only TCP/IP, but also POP3, SMTP and IMAP. These are the rules for handling emails. They make services secure and allow the development of email applications for smartphones and PCs.


Why get HTTPS proxies?


Dexodata is the infrastructure based on the best datacenter, residential and mobile proxies you can buy. The process of obtaining data goes through HTTPS or SOCKS5. HTTPS as the main browser protocol receives authentic content from most sites.

Every time our client orders to buy HTTP proxies, he gets the IP change option. External addresses rotate by the command sent via API or manually. Target sites treat requests as coming from different IPs, even if they are within the same geographic area. Automated data harvesting goes on without pauses, and sites are not overloaded with requests. In 2022, this allows you to comply with the policy of transparency and the legal geo targeted proxies use.

Among the HTTPS functions are:

  1. Internet speedup. Users who have purchased server proxies or get supreme proxies for a free test also have access to the reseller's cache. Site elements are loaded from it.
  2. Distribution of outbound requests. The load on landing pages is shared between proxies. Choose HTTPS proxy, buy it and apply to spread the load.
  3. Precise geo-targeting. Our infrastructure controls IP pools in a hundred countries. Geo targeted proxies are united in groups by city, provider or mobile carrier. For datacenter servers division involves pools by the same ASN.
  4. Internet server filtering. HTTP proxies filter out pages with inappropriate headers before they load the page body. It makes data acquisition faster and more reliable.
  5. Statistics retrieval. The corporate infrastructure like ours works with third-party applications, and tracks received and sent traffic. The logs store a list with pages visited with attributes.

HTTPS works consistently even in antidetect browsers, which deny HTML headers. These suit perfectly for collecting information without DNS requests, FTP and UDP. To handle the traffic faster one uses SOCKS5. Both protocols are available for every Dexodata free supreme proxy during trial period. Swap them when needed just by changing the IP port. The checklist includes locations in Canada, Netherlands, Singapore, Vietnam, Egypt, Australia and Italy. That is why our ecosystem is a trusted enterprise partner in everything that occurs gathering and processing web data at scale.
