IPv4 is 32 bits wide, or about 4 billion IP addresses; while IPv6 is 128 bits wide, or about 3.4x10^38 IP addresses. The number of addresses between the two has a difference of 79x10^27 times bigger. It is calculated that the world's energy output combined could only support using 1/3rd of the available addresses in this address space.
What else can I help you with?
Differential between ipv4 and ipv6?
1. Describe the main features that differentiate IPv6 from IPv4
Which statements about IPv4 and IPv6 are correct?
IPV6 is less vulnerable to DNS Spoofing IPv4 addresses use 32 bit or 4 bytes for addressing IPv6 addresses use eight bit segments.
What are the loopback addresses in IPv4 and IPv6?
In IPv4, the loopback address is 127.0.0.1. In IPv6 it is ::1.
What is IPv6 and when will it be used?
(Internet Protocol) IPv6 is the next step from IPv4. Currently we are not using IPv6 for our networks but soon it will implemented into our networks normally. IPv6 uses 128 bit spaces for its ip addresses were as IPv4 only uses 32 bit spaces. That means IPv6 can support 2128 addresses. I do not think we will run out of addresses with this version anytime soon.
Which characteristic describes an IPv6 enhancement over IPv4?
While IPv6 is based on IPv4, it is superior. The main characteristic that shows its enhancement over IPv4 is that it processes faster.
What allows IPv6 hosts to map host names to IP addresses?
DNS - it handles both IpV4 and IPv6 addressing.
What is the length in bits of a logical IP address IPv4 and IPv6?
32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).32 bits (for IPv4), or 128 bits (for IPv6).
IP ADDRESS occupies how many bytes?
IPv4 addresses are 4 bytes. IPv6 IP addresses are 16 bytes.
What is the length of IPv4 addresses?
IP addresses are of two types IPV4 and IPV6 . Depending upon the version the length of IP address differs . IPV4 is 32 bit long and IPV6 is 128 bits long.
Should ipv4 be disabled when using ipv6?
There is no need to disable ipv4 to use ipv6.
What protocol is able to resolve both computer names to both IPv4 and IPv6 addresses?
Netbios over tcp/ip
How many IPv6 address are possible?
In theory there are 264 available network allocations in ipV6. It is not known how many are actually in use at this time. For a very clear comparison, in IPv4 there is a total of 4,294,967,296 IP addresses. With IPv6, there is a total of 18,446,744,073,709,551,616 IP addresses in a single /64 allocation.
