### Parse domains and check TLDs with Domainatrex

Source: https://github.com/zensavona/domainatrex/blob/master/README.md

Shows how to parse host names into domain, subdomain, and TLD parts, and how to check if a string is a top-level domain. The examples include parsing 'someone.com' and 'blog.someone.id.au', and checking 'com' and 'someone.com'.

```elixir
iex> Domainatrex.parse("someone.com")
{:ok, %{domain: "someone", subdomain: "", tld: "com"}}

iex> Domainatrex.parse("blog.someone.id.au")
{:ok, %{domain: "someone", subdomain: "blog", tld: "id.au"}}

iex> Domainatrex.tld?("com")
true

iex> Domainatrex.tld?("someone.com")
false
```

### Configure Domainatrex in config.exs

Source: https://github.com/zensavona/domainatrex/blob/master/README.md

Customizes Domainatrex behavior in config.exs, including fetching the latest TLD list, setting a custom public suffix list URL, adding custom suffixes, and controlling private domain inclusion. The example shows all available configuration options with their defaults.

```elixir
config :domainatrex,
  # Explicitly allow compile-time HTTP request to fetch the latest list of TLDs (default)
  fetch_latest: true,
  # Download the public suffix list from the official source
  public_suffix_list_url: ~c"https://publicsuffix.org/list/public_suffix_list.dat",
  fallback_local_copy: "priv/my_app_custom_suffix_list.dat",
  # Add custom suffix for com.be
  custom_suffixes: ["com.be"],
  # Include private domains (default)
  include_private: true
```

--------------------------------

### Add Domainatrex dependency to mix.exs

Source: https://github.com/zensavona/domainatrex/blob/master/README.md

Adds the Domainatrex package to an Elixir project's dependencies. Use this in the deps function of mix.exs to install version ~> 3.2.

```elixir
defp deps do
  [
    {:domainatrex, "~> 3.2"},
  ]
end
```
