Is there a standard function to convert an IP address, say, 127.0.0.1 to a tuple,i.e. {127,0,0,1}?

The Erlang standard libraries include one that will convert a charlist. Perhaps it will meet your needs.
iex(123)> :inet.parse_address '127.0.0.1'
{:ok, {127, 0, 0, 1}}

:inet.parse_address/1
should do.
Sorry for not providing a link, for some reason I can’t get a link for it on mobile.

Many thanks, @NobbZ, for the solution.
I have a question…
why does the below not work?
:inet.parse_address “127.0.0.1”
{:error, :einval}
Because it is an Erlang function that does still only work on Erlang strings, aka charlists.
There has not been an update yet to allow for binary strings as well.
