When I get my IP address from Google, in most cases, it's a number like NNN.NNN.NNN.NNN (sometimes fewer than 3 Ns). It always is in that format. I noticed on this new wifi that my IP address is a completely different format according to Google (and ipconfig). It's formatted like the below (different numbers and letters):

Eight numbers, four on each side of a colon:

2700:5400:

Then five other colons, separated in four sets each separated by numbers and letters:

3i44:4n2n (and more)

In total, the format is like:

NNNN:NNNN:NlNlNl:NlNlNl:NlNlNl:NlNlNl:NlNlNl:NlNlNl

Where Nl represents either a letter or number

What does it mean when an IP is configured this way? In searching, I haven't found anyone posting an IP like this.

Thanks!

    Hello, that's an IPv6 address. And this is not a security question... – John Blatz Jan 2 '16 at 13:17

    Recommended reading: IPv4, IPv6, What questions can I ask about here?. The stackexchange website where this question would belong to thematically would be networkengineering.stackexchange.com but this question is so basic it would likely get quite a negative response there. – Philipp Jan 2 '16 at 13:46
  • @Philipp: I think that a better suggestion for such question would be SuperUser. From non IPv6 aware end-users, I can understand that IPv6 addresses may look strange ;) ! But this is clearly a question related to home and not corporate networking. – WhiteWinterWolf Jan 2 '16 at 16:36

This is not a security question.

The IP address you're getting from google, with the periods, is based on IPv4. The "other one with the colons" is based on IPv6.

Please read up on them. Hope that helps you.
