Thank you. Vipin, if this answer has answered your question, local etiquette is that you accept it by clicking on the tick outline next to it, thus driving the SF reputation system. My apologies if you already know this. Taking up a small part of the massive IPv6 address space, the private IPv6 is for special requirements and private use in IPv6 networks.

These private IPv6 addresses are only local to a specific link or site, therefore they are never routed outside a particular network. Based on their scope, private IPv6 addresses can further be divided into site-local and link-local addresses. The site-local address has the scope of an entire site or organization.

Link-local address, on the other hand, has a smaller scope and only refers to a particular physical link. When we have a look at them we realize that the main difference between public and private IPv6 addresses lies in their scopes.

In these addresses a bit random number is included in the address such that the probability that two sites that want to interconnect end up with overlapping address blocks is negligible. It appears the block was intended for addresses that are globally allocated but only locally routeable. However issuing of such addresses never happened. Another change from IPv4 is that use of NAT is strongly discouraged, there is an "Experimental" RFC for prefix translation but none at all for one to many NAT though there do exist implementations despite the lack of a standard.

The number of IPv4 IPs available is 2 32 , or 4,,, For IPv6, however, the number is 2 , or ,,,,,,,,,,,, That's a lot of IPs! Now that we know the number of IPv6 addresses there are, we can get to the anatomy of the IPv6 address The anatomy of IPv6 addresses IPv4 addresses are generally in quad-dot notation, e. IPv6 addresses use colons instead of dots and are larger that IPv4 addresses.
