"::1" is the IPv6 loopback address. If you haven't seen IPv6 addresses
before, they separate the parts of an address with ":" instead of ".".
Using two together ("::") is a shorthand for "fill all these bits with
zero" and it can appear only once in an address.You see the brackets "[]" in URLs because otherwise any URL parser would get confused by what's the address and what's the port. For example, is "http://2607:f8b0:4009:812::200e:8080"; telling you to connect to address "2607:f8b0:4009:812::200e" on port "8080", or address "2607:f8b0:4009:812::200e:8080" on the standard port 80? Brackets make this unambiguous: "http://[2607:f8b0:4009:812::200e]:8080/"; On Sun, Nov 20, 2016 at 8:53 PM, James Bennett <ubernost...@gmail.com> wrote: > It's the IPv6 loopback address.
