How do I add IPv6 address into System32\drivers\etc\hosts?

  • 772

There is already by default, and it works (Win 7):

::1             localhost

This also works (testing with ping):

::1             hosta

But when I'm trying to add something non-loopback, it doesn't resolve:

fe80::215:afff:fec6:ea64 realhost

So that I can do:

C:>ping fe80::215:afff:fec6:ea64
Reply from fe80::215:afff:fec6:ea64: time=2ms

But can't go with hostname that I put in hosts:

C:>ping realhost
Ping request could not find host realhost. ...

Any way to add an IPv6 address to hosts in Windows?

  1. Finally, I've found the way. I speicied zone ID (11 in my case) in hosts:

    fe80::215:afff:fec6:ea64%11 realhost

    Which I've got using

    netsh interface ipv6 show addresses

  3. According to a Microsoft TechNet article from 2005/2006:

    You should not place entries for link-local addresses in the Hosts file because you cannot specify the zone ID for those addresses. This concept is similar to using the Ping tool to ping a link-local destination without specifying the zone ID. Therefore, entries in the Hosts file are useful only for global or site-local IPv6 addresses.

  4. I don't have Win7 nearby so can't test it, but I got caught by the hosts.sam file once. Windows Explorer will hide extensions by default, so I spent a day editing the "hosts" file but it was actually the hosts.sam file. Make sure you are editing the real hosts file.

    And antispyware programs will block changes to the hosts file. Malware will add hosts entries to redirect bank websites to fake sites.

    Adding ipv6 addresses to the hosts file does work on W2K8, I did it last week.
