Homework? Best grab yourself one of the numerous subnet calculators available on the Internet. – John Gardeniers Feb 16 '10 at 23:09

use a mask calculator like http://cric.grenoble.cnrs.fr/reseau/calculemasque/ (in french, but terms are same) There is too some CLI tools (something like ipcalc)
$ ipcalc 174.121.25.208/29
Address: 174.121.25.208 10101110.01111001.00011001.11010 000
Netmask: 255.255.255.248 = 29 11111111.11111111.11111111.11111 000
Wildcard: 0.0.0.7 00000000.00000000.00000000.00000 111
=>
Network: 174.121.25.208/29 10101110.01111001.00011001.11010 000
HostMin: 174.121.25.209 10101110.01111001.00011001.11010 001
HostMax: 174.121.25.214 10101110.01111001.00011001.11010 110
Broadcast: 174.121.25.215 10101110.01111001.00011001.11010 111
Hosts/Net: 6 Class B

I'll give you the answer once, but if you are doing VLANing, you really should learn to do the math yourself.
174.121.25.209 - 174.121.25.214

First Usable IP Address = .....: 74.121.25.209 Last Usable IP Address = ......: 74.121.25.214
Look up CIDR notation in case you want to learn more about expressing addesses like this
