> Project: Traffic Server
> Issue Type: Improvement
> Components: DNS
> Affects Versions: 2.1.7
> Reporter: Alan M. Carroll
> Assignee: Alan M. Carroll
> Priority: Minor
> Fix For: 2.1.9

> The target structure is __ink_res_state in lib/ts/ink_resolver.h. The items
> to be removed are
> IPv6 nibble support. This flag and associated values are never checked
> anywhere else in the codebase.
> The nssocks array. This is a potential bug as it is never initialized but is
> used to close file descriptors.
> Sort list support which is also never used.
> The point of this is to avoid working on IPv6 support for things that aren't
> used.
