That's the per-interface setting, which is inherited from the default.

I'm confused though, since your disable IPv6/IPv4 question comes from a
10,000 foot management view of the system, but you're looking down in
the details of the input/output routines... you first need to understand
how to disable before you can jump right into the code details.

Take a look at Documentation/networking/ip-sysctl.txt and ipv6.txt for
some notes on the settings.
