For example you can address entire IPv4 address space under '''3.5''' network using address like '''3.5.x.x.x.x'''


You can also map IPv4 address space under particular network '''3.6.''' like '''3.6.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x'''.
IPv6 address space can be mapped under particular network '''3.6.''' like '''3.6.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x''' or
'''3.6.$0123.$4567.$89ab.$cdef.$0123.$4567.$89ab.$cdef''' or simply as '''3.6.$0123456789abcdef0123456789abcdef'''

Or IPv6 could be also mapped in various ways like '''3.6.$0123.$4567.$89ab.$cdef.$0123.$4567.$89ab.$cdef''' or simply as '''3.6.$0123456789abcdef0123456789abcdef'''

Motivation

Decentralization

  • Allow multiple address domains and inter-addressing. This should enable anyone to design own address registration authority. To communicate with other domains there is necessary to establish inter-domain addressing rules. Because length of address should be variable then anyone could map fully own top level address domain to other address domain.
  • Mapping entire address space into node in other address space.
  • Avoid single entity like IANA to rule entire global address space and charge for assigned address ranges.
  • Support inter-planetary addressing independent to single entity located on single planet

Dynamic address size

  • Allow variable length address.
  • Allow short address for embedded and IoT devices.

Dynamic address segment

  • Allow one address segment to be more then 256

Description

Usage of variable length numbers

Address notation

Address can be simply written as numbers separated by dots like: 1.22.36.4222.5.58

Here first number is top most address segment and further numbers are define lower levels of address. Address space can be imagined as tree where branches can grow as necessary. This allows mapping of one address space to another.

Network in address space 1: 4.55.2

Network in address space 2: 7.2.73

Mapped space 2 under network space 1: 4.55.2.7.2.73

Then for example host with address 4.55.3 can simply address host with address 4.55.2.7.73.5

Hexadecimal form

Big numbers can be written in hexadecimal form 1.$16.$24.$107e.5.$3a.

This allows also to use MAC address as unique host address. For example: 5.3.$fe45026371ec


Mapping IPv4 and IPv6

Thanks to dynamic nature, mapping of IPv4 and even IPv6 is possible. Address domain authority can define which network should hold other protocol addresses.

For example you can address entire IPv4 address space under 3.5 network using address like 3.5.x.x.x.x

IPv6 address space can be mapped under particular network 3.6. like 3.6.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x.x or

3.6.$0123.$4567.$89ab.$cdef.$0123.$4567.$89ab.$cdef or simply as 3.6.$0123456789abcdef0123456789abcdef

Potential problems

Entire address space scan

Entire Internet can't be scanned for reachability as address is dynamic and number of addressable nodes are nearly infinite. Also single network segment can be mapped to multiple other segments. Even there can be loops in addressing configured in router so entire address space can be mapped to subnetwork address. Then count of connected and reachable nodes in the Internet can't be easily counted. But this problem is similar in both IPv4 and IPv6.

Maximum address supported by routers

As address can have variable length and network segments could be huge numbers then it is important for packet to arrive to destination address if source and destination address is supported by routers. Each router or node have limited memory and have to support some maximum address range. There could be some basic recommended minimal supported size. It could be for example eight segments each with size 0-65535 (65535.65535.65535.65535.65535.65535.65535.65535) Which would be 128-bit long if it would be structure with static size.

If particular source or destination address is not supported by router then router should inform source node about the problem. So maximum supported address could be detected on single path.
