I do believe you need the "netmask" option, but the rest is just needed
once. But from reading interfaces(5) I think you further simplify by
writing:

,----
|  auto eth0
|  iface eth0 inet static
|          address 142.54.186.2/29
|          gateway 142.54.186.1
|          dns-nameservers 192.187.107.16 69.30.209.16
|  iface eth0 inet static
|          address 142.54.186.3/29
|  iface eth0 inet static
|          address 142.54.186.4/29
|  iface eth0 inet static
|          address 142.54.186.5/29
|  iface eth0 inet static
|          address 142.54.186.6/29
