Dexodata belongs to the range of the leading trusted proxy websites contacted by countless individuals and companies to buy residential and mobile proxies. Our datacenter proxies are best at serving enterprise needs.

The networking issue has become a proxy’s strong point. We mean the shortage of IPv4 addresses. But due to omnipresent NAT technology we serve 4G mobile proxies and residential without fear for their efficiency. Today we will tell why.

NAT technology and residential IPs to buy

There are only 4.3 billion IP of 4th generation available. Not much, bearing in mind:

  1. Earth population of 8 billion people
  2. Countless amount of intermediate devices maintaining the Web
  3. Increasing level of the IoT concept (Internet of Things), which implies involving all the household items in a single network.

NAT technology allows Internet Service Providers (ISPs) to routinely assign an IP to a significant bunch of users in a subnet. That is what the potential of it is all about.

NAT stands for “Network Address Translation.” It translates public addresses to private, and vice versa. It makes it possible for multiple Internet users to get connected to the global Net with identical IPs. Without it, ISPs would not be able to serve all their customers, as well as trusted proxy websites.


How does NAT operate?


NAT technology is implemented in every router. It provides internal IPv4 names. Then the algorithm translates a couple of them into a valid public IPv4 address. 

It means that requests from several sources are forwarded to the external network as one, carrying a single IP. The crucial takeaway is that behind any publicly visible address assigned by any Internet connection vendor, there will inevitably be many people. The exact number of such users has no theoretical limit, and depends on:

  • Network or router capability
  • Available bandwidth
  • Signal route, etc.

Web pages and services perceive only that public address. They are physically unable to recognize internal identifiers used behind the router’s barrier. That is true for common people, 4G mobile proxies and residential, and so on.

How does NAT technology work with proxies?

IP address #1, IP #2, and IP 3 are represented in the Internet as a single device with one IP due to the NAT algorithm 

Hence, while websites’ guarding algorithms can still flag any IP they deem to be suspicious, they won’t do that. Since this will affect multiple users.


NAT and IPv6 proxies


One may ask, if NAT fixes the IP shortage problem, why are there IPv6 addresses? They belong to a new generation of network protocols with opportunities to connect large amounts of connected gadgets. Dexodata already provides for free trial residential proxies and other types along with IPv4.

IPv6 still requires rerouting techniques, but on a larger scale. The developed addressing technology is called Carrier Grade NAT (CGN or CGNAT). It adds one more layer to the communication process. It goes this way:

  1. First, private IPs of users are translated into a single private address of the provider
  2. Then private providers’ addresses are united into a subnet with a united IP
  3. And finally, this IP becomes a public one.

Nowadays WWW is gradually moving from old online identification to its sixth generation, and CGNAT assists. The main role is to provide compatibility of IPv4 and IPv6 addresses due to the NAT444 solution. One can buy residential rotating proxies of both classes.


Why use geo targeted proxies today?


NAT is the reason to buy residential and mobile proxies via trusted proxy websites despite the growing number of web resources. Static servers are nothing more than a relic. If you want to ensure your privacy, you should leave them where they belong, literally in 2007. Sixteen years ago, they might have been a reliable and workable option. Now, not a single large web page will trust them and the addresses they provide.

Quite the contrary, site owners are quick to automatically recognize datacenter proxies from their individual ASN identification. Of course, these middlebox devices today can also rotate external IP, like 4G mobile proxies do, but they are not into the NAT technology. To work in social media and on strongly-protected e-commerce sites, it’s advised to buy residential and mobile proxies
