I'm sure the folks at Sonic Rim and Kathy's Cottage ( to name a couple ) appreciate your using their space to illustrate your question ;->
I'll ignore the couple of typos in there. it's late. you have an overlap in your first three subnets. 105.0/25 ( not /17 ) overlaps with 105.0/26 ( not 18 ) and 105.64/26 How many hosts do you need on each subnet? It is sometimes better to work backwards from there.

Since I am not very good and do not have much experience with IP addressing, I wanted to send this to make sure what I have is correct or if I am really wrong on this one. Thanks in advance for any feedback or corrections!! This is a new network- Current IP Address=65.85.105.0 Mask=255.255.255.0 I need a total of 5 subnets. What I did Took 65.85.105.0, 255.255.255.128 to subnet into 2 networks, This gave me Subnet 1= 65.85.105.0, hosts 1-126, broadcast 127 Subnet 2=65.85.105.128, hosts 129-254, broadcast 255 Took 65.85,105.128 255.255.255.192 to subnet into 4 subnets This gave me Subnet 1=65.85.105.0. hosts 1-62, broadcast 63 Subnet 2=65.85.105.64, hosts 54-126, broadcast 127 Subnet 3=65.85.105.128, hosts 129-190, broadcast 190 Subnet 4=65.85.105.192, hosts 193.254, broadcast 255 So this would give me to use on the network 1=65.85.105.0 255.255.255.128 (17 mask?) 2=65.85.105.0 255.255.255.192 (18 mask?) 3=65.85.105.64 255.255.255.192 4=65.85.105.128 255.255.255.192 5=65.85.105.192 255.255.255.192 Did I do this correctly? This is based on using subnet zero. I am using a public class A but for security reasons I did change the actual real address. Thanks again for everyones feedback. __________________________________________________ Do You Yahoo!? Check out Yahoo! Shopping and Yahoo! Auctions for all of your unique holiday gifts!
