Questions about IPv6, the newest version of the Internet Protocol. This tag should be used when asking about personal/home network IPv6 addressing, or basic IPv6 knowledge. Questions related to company-grade IPv6 networks are off-topic and should be asked on Network engineering SE.
The length of an IPv6 address is 128 bits, compared to 32 bits in IPv4. Therefore the address space supports 2128 or approximately 3.4×1038 addresses. This means that many more devices can be connected directly to the Internet.
A typical IPv6 address would be represented like this:
fe80:0000:0000:0000:0202:b3ff:fe1e:8329
but there are rules for shortening the address such as removing leading zeros:
fe80:0:0:0:202:b3ff:fe1e:8329
or replacing consecutive groups of zeros with a double colon:
fe80::202:b3ff:fe1e:8329
