Know IPv8, the new concept of the Internet. 🍋

Although IPv6 was developed to solve the IP Address shortage and has been pushed for more than 20 years, the key limitation is that it does not directly support IPv4, delaying the global Internet transition. Most recently, there has been a new proposal from IETF in Internet-Draft form under the name Internet Protocol Version 8 or IPv8 that seeks to solve this problem with the full "backwards supported" concept.

.

IPv8 is designed to use a 64-bit address structure divided into Routing Prefix and Host Address in r.r.r: h.h.h format. The key point is that IPv4 is viewed as a subset of IPv8. For example, if zero prefix is defined, the system will immediately interpret it as IPv4, resulting in the original device and system being available without modification, reducing the cost of upgrading and eliminating the need for a major one-day transition.

.

Structurally, the IPv8 network offers ASN number holders a large addressable, level / 32 area that amounts to more than 4.2 billion addresss. this concept allows for more organized routing management, reducing the size of the global routing table and reducing the burden of core routers that have to manage enormous amounts of routing.

.

Another key concept is the "Zone Server" that combines core network services like DNS, DHCP, NTP, and identity authentication systems into one platform, reducing administrative complexity. Meanwhile, a new routing algorithm called Cost Factor (CF) is proposed that looks at both network congestion and physical distance to help optimize and detect abnormal paths.

.

In security, IPv8 changes the concept of requiring authentication via token before sending data, and packets must be verified through systems such as DNS8 and WHOIS8 that reduce source and botnet spoofing problems from the source. Even DDoS attacks can occur, they are more difficult to do in terms of identity hiding.

.

However, IPv8 is now only a proposal at the Internet-Draft level, not yet a practical standard, and it still needs to go through a lot of consideration, as a whole, as an interesting concept as a "new vision of the Internet" that tries to solve the same problems as a system-wide overhaul, rather than something that will actually happen in the short term.
