You defined the base address as 70.87.206.50.
Then re-defined the base adddress (that's what the ":0" means) to be 
70.87.206.51...
Which isn't a valid thing to do...
Remove the original entry and replace it with the following:
#Base address
auto eth0:0
iface eth0:0 inet static
      address 70.87.206.50
      netmask 255.255.255.0
      gateway 70.87.206.49
#Alias adress #1
auto eth0:1
iface eth0:1 inet static
      address 70.87.206.51
      netmask 255.255.255.0
      gateway 70.87.206.49
#Alias adress #2
auto eth0:2
iface eth0:2 inet static
      address 70.87.206.52
      netmask 255.255.255.0
      gateway 70.87.206.49
#Alias adress #3
auto eth0:3
iface eth0:3 inet static
      address 70.87.206.53
      netmask 255.255.255.0
      gateway 70.87.206.49
#Alias adress #4
auto eth0:4
iface eth0:4 inet static
      address 70.87.206.54
      netmask 255.255.255.0
      gateway 70.87.206.49

Don;t know why you need to put all of them on a single interface...
But that should work.
