IPV6

Internet Protocol version 6

has a 128-bit address space, which is 340 undecillion addresses. An

IPv6 address looks like this: 2001:0db8::53. Where there are two colons

side by side, all the segments in between contain only zeros. So without

the double colons, you would expand the example address to 200

1:0db8:0000:0000:0000:0000:0000:0053.
