## Will IPv6 eventually run out of addresses explain?

Will IPv6 addresses run out eventually? In practical terms, no. There are 2^128 or 340 trillion, trillion, trillion IPv6 addresses, which is more than 100 times the number of atoms on the surface of the Earth. This will be more than sufficient to support trillions of Internet devices for the forseeable future.

## How many IPv6 addresses are left?

IPv6 uses a 128-bit address which allows for 2128 , or approximately 3.4 x 1038 addresses. 3.4 x 1038 is equal to 340 undecillion IP addresses. Therefore, there are 340,000,000,000,000,000,000,000,000,000,000,000,000 IPv6 addresses.

## Does IPv6 have private addresses?

In IPv6 we don’t have an exclusive choice between assigning a network interface an internal private address or an external public Internet address – known as an IPv6 Global Unicast Addresses (GUA) (RFC 4291).

## What is a 192.168 IP address?

192.168. 1.1 is a common factory IP address for a consumer-grade router. If the router is used for connecting to the Internet then all computers and devices which access the Internet through it will use this address as their default gateway.

IANAThe IPv6 address management function was formally delegated to IANA in December 1995 [RFC1881]. The registration procedure was confirmed with the IETF Chair in March 2010. As stated in RFC3513, IANA should limit its allocation of IPv6-unicast address space to the range of addresses that start with binary value 001.

## Do you need to subnet IPv6?

If you are given a /48 subnet to work with, you will have more than enough spaces to work with i.e. you get 65536 subnets with 18,446,744,073,709,551,616 hosts per subnet. … So, in all, subnetting is necessary in IPv6, but not for the reasons why we did it with IPv4.

For DHCP, it actually depends on the settings of your DHCP server. There is something called address reservation. However, if your IPv6 prefix is assigned dynamically by your ISP, you should not set it statically on your device.

## Should I turn on IPv6?

Best answer: IPv6 can potentially add support for more devices, better security, and more efficient connections. While some older software may not work as expected, most of your network should work fine with IPv6 enabled.

## How many IPv6 addresses should I have?

It all depends on what you’re using IPv6 for. The bare minimum to do anything is a single link local address. If you want to route traffic you’ll need a minimum of one link local and one global address of some flavor. However, it’s probably much more common, in practice, to have more than 2 addresses these days.

## Why does my IPv6 address keep changing?

This is completely normal and there is nothing to be worried about. If these frequent IP changes are causing you trouble, you may want to contact your ISP and inquire about upgrading to a static address.
