About this tool:
RFC 4193 Compliant IPv6 Local Range Generator
Generate local IPv6 addresses and lists. Deploy IPv6 network with ease with this IPv6 tool.
The tool helps the user to generate a local IPv6 address for use in your local environment. That proves very helpful when it comes to using IPv6 on local machines.
IPv6 is expanding in Asia as India and China are the biggest adopters of IPv6. The deployment stat shows that some countries that were not pioneers or leaders in the IPv4 Internet have adopted IPv6 even earlier than some other countries in Europe. Focusing on a single internet system also reduces the cost of maintaining the two systems.
The world is focusing on IPv6 only by 2025. And there are always be the first movers, especially the mobile network operators (MNOs), that could not get many IPv4 addresses. So now, the verticals that will move to 5G will automatically get the IPv6 support with 5G.
Private IPv6 address range
IPv6 address space is so huge. IPv6 size is 128 bits. That means it can provide 340 undecillion (36 zeros) addresses. In other words, the IPv6 address offers 1,028 times more addresses than the IPv4 address. And everyone can be able to get the IP address for each of the devices it owns.
Therefore, theoretically, it wouldn't be necessary to have private IPv6 addresses like IPv4 addresses (192.168.x.x or 10.x.x.x).
However, until you do not receive an IPv6 address range from your ISP, you may want to use "private" addresses for internal networks and testing, etc.
For generating the complaint local IPv6 addresses for your private use, the process is simple, RFC 4193.
- Open the Local IPv6 Address Generator Tool.
- Enter the Global ID: Any valid alphanumeric string of 10 characters consists of 0123456789abcdef.
- Enter the Subnet ID: Any valid alphanumeric string of 4 characters consists of 0123456789abcdef.
- Click on the "Calculate" button.
- The tool provides you the Prefix / L, Global ID, Subnet ID, Network, CIDR, IPv6 Address Format, Start Range, End Range, and Block Size.
Note: The "Global ID" and "Subnet ID" should be random to assure uniqueness.
No doubt, currently we are running two internet systems, IPv4 and IPv6. But it's clear and does not make any sense to run two internet systems simultaneously, the IPv4, which is old, an aging and broken one, and IPv6, which is new, fresh, and designed with a clean slate approach. The early adopters were Google, Facebook, and Microsoft, followed by many ISPs and MNOs. Today, ICANN requires that all new TLDs must be IPv6-capable from the day they start. In addition, the hosting companies are also providing free IPv6 services. So without any doubt, the future is in IPv6.
However, the IPv4 will always remain to work, which is undoubtedly the beauty of Internet Protocols.
