Add blank page in latex without page number

To add blank pages / empty pages in latex, we can do this:

\documentclass[11pt, a4paper]{article}

\usepackage{fancyhdr}

\begin{document}

This page one

\newpage

%---------------------

\fancyhf{}

\thispagestyle{empty}

\newpage

\mbox{}

\newpage

%---------------------

\setcounter{page}{2} % This reset the page number counter.

\newpage

This is page two after one blank page without numbering.

\end{document} 

Of course, there are ways to put words like "This page is intentionally left as blank."
