Assuming that the site has an IPv4 address. One of the reasons for introducing IPv6 is that internet ran out of addresses; there is not one for everyone. In the years to come, we will see an increasing fraction of DNS entries having IPv6 addresses only. At work, we have so many machines that we have consumed the IPv4 addresses allocated to us, so they have IPv6 addresses only.

Another aspect with IPv4 vs. IPv6: The lack of IP addresses have lead a lot of ISPs to allocate IPv4 addresses temporarily, on demand, to their customers. The address you use today, someone else may use tomorrow. If you offer a service, you have to pay extra for a fixed IP address. Lots of companies dynamically translate a fairly small number of external IPv4 addresses to a large set of internal addresses.

With IPv6 there is no technical need for doing such temporary / dynamic allocations; all devices will (/may) have persistent IPv6 addresses. So if you have looked it up in DNS once, you may keep the translation "forever" in your local cache, and will not depend on DNS again for that address.

This is certainly not by definition; even IPv6 addresses may change (or e.g. a given service is taken over by a different device), but there is far less technical need to update or translate the IP address. Our dependence on DNS stability will be significantly reduced, once static IPv6 addresses are commonplace.

That also means that authorities who want to ban certain web sites will have far less use of DNS censorship; if you have obtained the IPv6 of some illegal site once, you don't need DNS any more. On the other hand: If you had one IPv4 address yesterday, another one two days ago, and a third one today, that would to a certain degree mask your use of dubious services. When you get yourself a fixed IP address, it is far easier to identify the traffic going to you from anywhere along the route, without tracing how your IP address changes over time.
