Does IPv6 eliminate NAT?

Myth: The lack of NAT in IPv6 reduces security Because NAT exists to overcome a shortage of IPv4 addresses, and because IPv6 has no such shortage, IPv6 networks do not require NAT.

Does NAT use when switching over to IPv6 make sense?

You can use NAT with IPv6, but it makes little sense – if you can live with NAT, why would you switch to IPv6 at all? However, without NAT, then no “firewall effect”, flimsy as it could be. Most operating systems are now IPv6 ready, and will use it automatically if given the chance.

What is the point in switching to IPv6?

Increased customer loyalty, higher network efficiency and reduced costs can all be powerful byproducts of the IPv6 transition. “Specifically, for many organisations this will mean configuring one or more web servers with IPv6,” Coffeen continues.

Is IPv6 better than NAT?

The key advantage of IPv6 is that its addresses are 128 bits in length, as opposed to the 32-bit length of IPv4 addresses. Nat offers the ability to share a single public, globally routable IP address among many internet hosts. This is valuable in the IPv4 world, where public IP addresses are, by necessity, conserved.

Why NAT is important?

NAT is a very important aspect of firewall security. It conserves the number of public addresses used within an organization, and it allows for stricter control of access to resources on both sides of the firewall.

What is the advantage of IPv6 over IPv4?

Advantages of IPv6 over IPv4

Why IPv6?	IPv4
IPv6 has more addresses	4.3 billion addresses
IPv6 networks are easier and cheaper to manage	Networks must be configured manually or with DHCP. IPv4 has had many overlays to handle Internet growth, which demand increasing maintenance efforts.

Which is better IPv4 or IPv6?

IPv4 provides an addressing capability of approximately 4.3 billion addresses. The Internet Protocol version 6 (IPv6) is more advanced and has better features compared to IPv4. It has the capability to provide an infinite number of addresses.
