Hello,

The wiki is not clear on this. Can specific ipv6 addresses be allowed  
and/or denied?

Yes.

Changes with nginx 1.0.3 25 May  
2011

```
[...]

*) Bugfix: a segmentation fault occurred in a worker process during
   testing IPv4 address mapped to IPv6 address, if access or deny 

```

rules  
were defined only for IPv6; the bug had appeared in 0.8.22.

Changes with nginx 0.8.22 03 Nov  
2009

```
[...]

*) Feature: the "access" and the "deny" directives support IPv6.

```
