How to disable the very little-known AT&T setting that can appear to hijack your home DNS lookups and redirect to 104.239.207.44

Issue

DNS queries on home network suddenly resolving hosts to 104.239.207.44.

Symptoms

You will see SPORADIC mis-resolutions of EVERYTHING to that 104.239.207.44 address if their crappy router happens to hear your PC's DHCP request - EVEN IF ANOTHER DHCP SERVER ON THE NETWORK assigns the ultimate address.

// TUPLE MICRO-BENCHMARKS, based on https://www.dotnetperls.com/tuple-keyvaluepair

// Tuples are generally fastest.
// ValueTuple is fastest in the particular case of GetHashCode.
// KeyValuePair is always worst.

// RAW RESULTS
// Numbers in milliseconds (lower is better)

How do you POST a JSON file with curl??

You can post a json file with curl like so:

curl -X POST -H "Content-Type: application/json" -d @FILENAME DESTINATION

so for example:

jammycakes

    /// <summary>
    ///  A <see cref="Lazy"/> object that implements <see cref="IDisposable"/>.
    /// </summary>
    /// <typeparam name="T">
    ///  The object being lazily created.
    /// </typeparam>

    public class LazyDisposable<T> : Lazy<T>, IDisposable where T: IDisposable
    {
        /// <summary>
