Visitor to Web site (Log showing Strange IP Address)

Amidst all the IP addresses in the visitor log to the web site, I saw this:
2604:2000:e100:200:c9fc:51b7:15eb:911b

That does not look like an IP address.
What visited my web site, if that's not an IP address or PC?

You can see some of the technical benefits in this WIKI article.

https://en.wikipedia.org/wiki/IPv6

There are so many IPv6 addresses that every device will have an address. There are so many devices, that the address space had to be enlarged.

That is an IPv6 IP address. Nothing to be concerned over.

Hi John:
do IPv6 addresses give off any more information than IPv4?
Does the site owner have the capability of determining what type of hardware the visitor is running, etc?

IPv6 just allows more IP addresses from a particular point.

Second question:  Possibly. They know here what my IP address is and Microsoft knows what OS I am running. Lenovo knows what hardware I am running. But that is not from the IP address at all.

IPv6 is only designed to accommodate more real ip address as IPv4 have been used up already.

Whether you can detect the client hardware, it depends on whether the user of the client machine allowed you to install an agent in their client machine.

Normally, you cannot do so as most antivirus  software will detect the install of agent as malware. Only if you provide something, i.e., benefits in exchange to the user, say you provide some content for them to download via your client software to be install before they can have the access to your content, you will be able to collect the info required.

Otherwise, you can only detect their browser and ISP details.

This page http://www.useragentstring.com/pages/useragentstring.php shows 'User Agent Strings' that browsers send to the web site when they make a request.  This happens for IPv4 and IPv6, it's just part of the process.  Are you trying to hide something?

The above IPv6 addresses only give info that the client machine is using ISP of Times Warner Cable.
