WebIt functions similarly to IPv4 in that it provides the unique IP addresses necessary for Internet-enabled devices to communicate. However, it does have one significant difference: it utilizes a 128-bit IP address. Key benefits to IPv6 include: No more NAT (Network Address Translation) Auto-configuration. No more private address collisions. Web1 mrt. 2024 · With so many addresses in IPv6 there isn't the same need for address conservation as there is in IPv4. You can assign a /64 to a point-to-point link and not feel guilty. The only exception to this is the recommendation from ARIN to use a /128 on loopback addresses. This gives us one block of hex digits, or 16-bits, to use for subnetting.

WebIf you remember you math lessons and exponents 2a x 2b = 2a+b. So given the above, one /64 IPv6 subnet can have 2 64 addresses: 2 64 = 2 32 x 2 32. 2 64 = (one Internet) x (4 billion) So one IPv6 subnet can hold the equivalent of 4 billion Internets.
