The Internet is evolving, one technology is being replaced by another. At first was the Web 1.0 era, built exclusively on HTML texts. It has been replaced by social networks, cloud storages, mobile apps in Web 2.0. Then came the “Internet of Things” (IoT), Web 3.0. Intermediary sites have given way to corporate platforms. Semi-legal sector turned to ethical transparent procedures in data search. Epoch of ISP, domestic and mobile proxy networks, such as Dexodata, offering to buy proxies for geo surfing.
In 2022, HTTP hypertext protocol received a third standardized iteration, HTTP/3. However, IP technology is still relevant, even if the network switches from TCP to UDP. Therefore, interest in gaining data through IPv4 and IPv6 protocols will persist. Our article is devoted to their features.
Information on the Internet is controlled by protocols. These are sets of rules for encoding, transporting, decrypting and displaying digital messages. They are divided into layers resting in a stack, like rungs on a ladder.
The distribution of protocol's layers in a stack
As seen in the picture above, IP is a network layer. It issues addresses to every device. So users, sites or Youtube proxies acquire locations on the Internet map to get messages.
We have two network layer protocols types, IPv4 and IPv6. You can buy residential IPv6 proxies or test supreme proxies for free. In the early 2000s, everyone had IPv4, it was enough for subnets. But this has changed when the user's number started increasing rapidly.
This IP address operates on 32 bits, consists of four numbers (octets) and colons between them. E.g. 220.127.116.11. Limit for a single element is 255. These are range limits also. In total, there are 4.3 billion IPs in the world, while the Earth population is 8 billion. Don’t forget intermediate interfaces network, incl. mobile network proxies. That’s why the new IPv6 was created.
You can get it easy. Just like running the data collection with Dexodata. The address is 128 bits. The total IP amount is 1028. (enormous huge number, may I say!) The margin will last for decades.
The title contains 8 hexadecimal values. They are separated by a colon, for example: 1FA9:FFFF:2621:ACDA:2245:BF98:3412:4167. Zeros in the designation agreed to be reduced. There are more types of residential IPs to buy.
The IPv4 address peculiarity is that one IP can be used by two or more devices. They have their own internal host-port. For communication with the outside world the external analogues are used.
The router is responsible for delivering information. It examines headers over each packet to distribute them to recipients. Proxy servers for Youtube, social media, marketplaces, etc. are organized in a similar way through backconnect IPv6 NAT proxies Dexodata applies to IP addresses. Intermediary changes the host within a known local pool automatically or upon request.
It seems that NAT is not needed for modern communications, since geolocated identifiers are found in abundance. However, this is not entirely true. Similar technologies (NAT66, NPTv6) have been developed for this protocol to be implemented in subnets with two or more firewalls. To buy IPv6 proxy is also possible.
It is hard to give unambiguous preference to one protocol. Everyone has useful features. You should check out an IPv4 because:
- Most endpoints operate it online. Therefore it’s compatible with a long app list.
- The infrastructure for receiving and processing data works more reliably. Mobile network proxies are considered as high-trusted by websites.
- The IPv4 network is easy to scale by connecting new online nodes, e.g. Youtube proxies.
- One address can be shared between two or more clients via NAT.
IPv6 has the following benefits:
- The absence of NAT can increase security. The managing algorithm here is improved.
- It speeds up dealing with video streams or game servers. The ping is lower due to modern internal architecture.
- Packets are less likely to be lost. IPv6 has a built-in algorithm, so control on TCP level is no longer necessary.
- It provides access to resources banned for IPv4.
However, you can detect errors after the launch of a multi-threaded data collection stream. I mean working with sites on IPv6. The reason is that version has not yet become popular everywhere.ipv6 nat proxy
A proven web ecosystem provides customers with two intermediary types. You should buy rotating IPv6 proxies by Dexodata to access new online resources or IPv4 proxies for most other cases. Consider our best datacenter proxies we provide within the Partner program you can make money on. But if target resources support mostly IPv6, this will complete information search faster. You will spend less time on the process, save money, thus faster gain profit from partnership with us.
