comcast router dhcp

I have a Comcast router SMCD3G-CCR P/N 7529244NA
DHCP is issuing out 192.168.1.10 to 192.168.1.199
I have a computer that I would like to use a static IP on so it does not change.

Can I reserve an IP in the router's DHCP or should I simply us an IP address outside the DHCP sequence
Example: use 192.168.1.9

I am not familiar with your router but most allow you to create a DHCP reservation.  Reservations are my preference as that way all IP's and devices are present in the address lease table for management purposes, and there is no need to keep documentation of static IPs elsewhere.

If you wish to manually assign an IP doing so outside of the DHCP scope range is best but it shouldn't be necessary as the router should ping/test that IP address to see if in use before assigning to another device.  However with some routers that doesn't always work as it should.

I agree, I'm only asking because I cannot find reserve settings in the router
I'll try leaving the PC with assigned IP and not make it static to see if the router does what it's suppose to do. Thanks

Usually you can find a manual on line, which I did look for, but couldn't find.  I just looked again and the closest I could find, SMCD3G ( http://k3sj.wordpress.com/smc-d3g-on-board-guide/#private ) doesn't seem to offer the capability to assign reservations.  I had not noticed the '3G' before.  Many of these do not.  Best bet is a static IP, and to play it safe keep it out of the DHCP scope IP range.
