You may think you bought 8 ip's, but you can only pass traffic on 6... That is how it works... You buy 16, and only 14 work. The first and last address are as Johnny said...

Thank you all for your time ...
But I have another question:
Why is a difference in setting up with icfg-eth0:0 and ifconfig ? As I sad, setting up all 8 IP-s with ifconfig works perfectly. Why if I specify explicitly the subnet mask in ifcfg-eth0:0 then appear other?
Thanks
