66 in decimal = 42 in hexadecimal (42h) 240 in decimal = F0 in hexidecimal (F0h) to mask is a way of saying to AND the 2 numbers.  Or in other words, the 1's in the mask tell you which bits to pay attention to and the 0's tell you which bits to ignore.  42h AND F0h = 40h = 64 decimal. So, what you are seeing is correct.   You need to use a mask of 255.255.255.255 to set a vlan association for a specific IP address.
Hi, I have a Powerconnect 6224 & need some help with routing configuration. Basically 1 port on the switch (port 17) comes from our Data Center provider that has say 15 public ip addresses. What I need is for those ip addresses to be divided to 3 nics. In other words Port 18 needs to have 1-5 public ip addresses, port 19 needs to have 6-10 public ip addresses & port 20 needs to have 11-15 public ip addresses. Obviously I would put those IP addresses on the relevant nics but need to sort out the routing inside the switch. The data centre can only provide me with 1 link (port). Is it possible to have 1 vlan then 3 other vlans inside the origonal vlan? Does Windows Hyper V Virtual network vlans link to vlans on the switch so they operate on the 1 network? Im new to layer 3 switches & would appreciate any assistane on setting this up. Thanks in advance Todd
