I would like to add a relevant information (someone may look for it):

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

A more general problem has been solved here, for $1/(1+cx^n)$ and $1/(1+cx)^n$, for any $n$:

You can find there the explicit formula for the probability density function, the monotonicity properties of the pdf, the first and second moments for $n=1$ and $n=2$.
