Why do DHCP addresses are required to be reconfigured sometimes

Question

I was reading about DHCP somewhere and found that it provides dymically the IP addresses from the available addresses (which I probably configure in my router setup normally ranging from 192.168.1.2 to 255) but sometimes I get some dummy address like 10.x.x.x instead of proper address as 192.x.x.x. So in that case either I need to repair the address with ipconfig command or statically assign the IP address. Why do I need to do so? Is there any issue with DHCP or its issue with my router? How can I correct it??

Also same kind of issue I face when I connect my system with my android's wifi and mostly I have to put static address like 192.x.x.x.

Thanks

Most probably you have another DHCP server running in your network, in addition to the one on your router, which assigns the 10.x.y.z address.
