Anyone know how to find the TTL for a DNS record with :inet?
I’m learning my way around :inet and :inet_res to perform DNS lookups but the documentation is a little confusing. Getting the value for the records themselves is straightforward enough, but I can’t figure out how to find the TTL values for each of the records.
Anybody ever figure this out?

:inet_res.resolve should give you the TTL for each record it returns.
For example, in:
iex(1)> :inet_res.resolve('elixirforum.com', :in, :a)
{:ok,
{:dns_rec, {:dns_header, 1, true, :query, false, false, true, true, false, 0},
[{:dns_query, 'elixirforum.com', :a, :in}],
[
{:dns_rr, 'elixirforum.com', :a, :in, 0, 28537, {78, 46, 110, 60},
:undefined, [], false}
], [], []}}
28537 is the TTL
