/etc/hosts equivalent for IPv6?

[Nermal]

My ISP now offers IPv6 and I've noticed that entries in /etc/hosts aren't respected any more. For example, I have "0.0.0.0 www.facebook.com" in there, yet I can still open the site in my browser (Safari).

ping www.facebook.com correctly gives an error, but ping6 www.facebook.com connects successfully. I've found a couple of comments saying that the file is ignored when using IPv6, but haven't been able to find any information on what to do about it.

Is there another file somewhere that works for IPv6? Or is there a setting I need to enable somewhere?

What is the proper way to display IPv6 Addresses in /etc/hosts

I've been tasked with writing a document on IPv6 for my colleagues to learn how to configure IPv6 addresses on our hosts. We primarily use RHEL6.x/7.x, ESXi, and Ubuntu Server. This only pertains t...

Nothing changes when the address is an IPv6 address instead of a legacy IPv4 address. The format is the same.
For example:

2001:db8:1::1 example.com www.example.com
2001:db8:2::1 mail.example.com
"

Thanks

It looks like "If you have a dual-homed address (where a host listens to both IPv4 and IPv6), you will have to enter it twice, once for the IPv4 address and once for the IPv6 address" could be the trick. I'm away from my Mac at the moment but will give it a go when I can.

Edit: I can confirm that this works

I haven't done it in a while, but I remember I had to put a v6 addr in brackets in the browser. Just an FYI in case you try an addr instead of a name you're resolving.

All good; that's the other way around which isn't a problem
