static ip addresses and dhcp range

Should static IP addresses be set outside of the DHCP range?
My current static IP address is inside the DHCP range and I think this may be causing some problems.

Yes static IP addresses should be outside the DHCP range to minimize conflicts. I'm sure some equipment isn't subject to these problems but I've encountered your issue first hand.

Which DHCP server do you use?

Not sure VladSun, the one from the router?

If you're talking about a linksys/netgear etc. router then yes. I usually set DHCP to start at 100, or maybe 10 depending on how many statics you need. The router would be .1 and then I have up to 100 for statics. Microsoft and other enterprise DHCP servers allow you to configure static/permanent leases so that the DHCP server gives out the same IP address to the the configured MAC address. But on small home/office equipment you need to reserve some addresses for static use or the router can lease out the one that you are using as static, thereby causing a conflict.

If you just want to have a static IP, you may just set a MAC/IP pair in your router (DHCP settings). Then you'll get the same IP, though its dynamically assigned.

I use the Linksys WRT54G2 and it doesn't have this option.

Yes, I'm using a linksys WTR54G router.
Going to assign outside of the DHCP range and see if it fixes my problem (sometimes internal ip address conflict, and turning the playstation on/off resets the internet).

Holy crap! I wondered what happened to the Internet sometimes. Leave the Playstation on!

This seems to have resolved the issue!
That darn problem has been bugging me for years.
