Oops, apparently this invocation wasn't good enough for IPv4?

I tried to copy this change to the main Dress to Impress apps, and it
like SUPER broke them, even though I've seen sources say this should
work for both IPv4 and IPv6?

Clearly I'm missing something, but this was the change to get things
working again over there, so I'm gonna copy them over here too for good
measure.
