networking-calico-1.4.2-1.el7.centos.noarch.rpm looks like a very old version - are you sure you really want that particular version?

That said, the Calico team (including me) hosts RPMs at https://binaries.projectcalico.org/rpm/, and that particular version can be found at these subpaths:

./calico-2.0/noarch/networking-calico-1.4.2-1.el7.centos.noarch.rpm
./calico-2.1/noarch/networking-calico-1.4.2-1.el7.centos.noarch.rpm
./calico-2.5/noarch/networking-calico-1.4.2-1.el7.centos.noarch.rpm
./calico-2.2/noarch/networking-calico-1.4.2-1.el7.centos.noarch.rpm
./calico-2.3/noarch/networking-calico-1.4.2-1.el7.centos.noarch.rpm
./calico-2.4/noarch/networking-calico-1.4.2-1.el7.centos.noarch.rpm

Best wishes,
