In computer networking, an IP version 6 address is how many times larger than an IP version 4 address?

An IPv6 address is 128 bits long while an IPv4 address is 32 bits, so it is four times larger.

Dividing 128 bits by 32 bits gives exactly four, which is the size multiple asked for.

A factor of 2 would mean 64 bits, which is not the IPv6 length.

A factor of 6 or 8 would need 192 or 256 bits, neither of which matches IPv6.

The larger address space lets IPv6 supply vastly more unique addresses than IPv4.

IPv4 offers about 4.3 billion addresses, a pool exhausted by the growth of connected devices.
