What do IPv6 addresses look like?
An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits (two octets, a group sometimes also called a hextet). An example of an IPv6 address is: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
What is IPv6 Gua address?
IPv6 Global Unicast Addresses (GUA) are always in the range of 2000::/3 and start with the hex digit “2” or “3” in the most significant hex digit. For these global unicast addresses, it is common for the left-most high-order 64 bits of the address to represent the network segment that is used for a link.
Which is the correct IPv6 address notation?
The IPv6 address size is 128 bits. The preferred IPv6 address representation is: x:x:x:x:x:x:x:x , where each x is the hexadecimal values of the eight 16-bit pieces of the address. IPv6 addresses range from 0000:0000:0000:0000:0000:0000:0000:0000 to ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff .
How do you read an IPv6 address?
IPv6 addresses An Ipv6 address uses 128 bits as opposed to 32 bits in IPv4. Because an hexadecimal number uses 4 bits this means that an IPv6 address consists of 32 hexadecimal numbers. These numbers are grouped in 4’s giving 8 groups or blocks. The groups are written with a : (colon) as a separator.
How do you simplify IPv6 addresses?
Compress consecutive hexadecimal fields of zeros using Double colon: IPv6 addresses can be further simplified by using double colons (::) in place of a series of consecutive hexadecimal zeros.
What is the range of IPv6 address?
128 bits
IPv6 addresses are each 128 bits long. Because each digit in an IPv6 address can have 16 different values (from 0 to 15), each digit represents the overall value of 4 bits (one nibble), with 32 digits total. As with IPv4, CIDR notation describes ranges in terms of a common prefix of bits.
How do you know if it’s IPv4 or IPv6?
Comparing IPv6 vs IPv4, IPv4 is 32 bit binary number while IPv6 is 128 bit binary number address. IPv4 address are separated by periods while IPv6 address are separated by colons.
Is 2000 :: A valid IPv6 address?
The 2000:: (in particular, 2000::/3) is just a prefix and is not a valid IPv6 address.
