Weird IP Addressses

**travel1241** · 16 Jan 2020, 10:28 PM

When looking at the module, "Who's online", I get a list of weird IP addresses whether it be a spider or a guest. I have searched and search for an answer here and on google and I cant find where the problem is.

All of my guests and spiders have this in front of all of the the IP addresses online and I'm not sure how to fix it. Thank you! :)

::ffff:148.251.120.201

nothing weird.

i would look up ipv6 as opposed to ipv4.

... or that ::ffff: prefix on that IPv4 address means that the admin's character set isn't set up to display that ghost/guest icon.

no, lat9, that's not right.... i never see a ghost/guest icon. just: ¥Guest

a search of ::ffff: on the web returns:

Short, casual answer: It's an IPV4 address mapped through a IPV6-compliant system.

from:

is.gd/5BReLQ

one can see more detail here:

best.

Okay, so I have nothing to worry about.

"Quote"

In the near future, IP addresses will all be IPv6, this is because we are nearly out of numbers (4.2 billion, minus some space for misc. purposes) in the IPv4 address space.

IPv6 allows for a much larger space. "340 undecillion ought to be enough for anyone" - Bill Gates speaking on IPv6.

It is important to start addressing IP addresses using the IPv6 namespace and therefore include the ::ffff: in your code because in the future there will be real hexadecimal data between those colons. If you strip it off for aesthetic reasons, your code will break when it switches to an IPv6 network or it's confronted with an IPv6 address.
