Dereference of a possibly null reference.

Cannot convert null literal to non-nullable reference type.

Possible null reference assignment.

Nullability of reference types in type of parameter 'obj' of 'int HostName.CompareTo(object obj)' doesn't match implicitly implemented member 'int IComparable.CompareTo(object? obj)' (possibly because of nullability attributes).

Nullability of type of parameter 'obj' doesn't match overridden member (possibly because of nullability attributes).

Cannot convert null literal to non-nullable reference type.
