The first few bytes of a MAC address (unless overridden) supply manufacturer and device type that a discriminating DHCP server could use to allocate devices into different address ranges.

The subnet could be large enough that both address ranges could be within the same subnet.  So, it may not actually be different subnets.  Further, trying to have a router administer multiple subnets could be a difficult thing to configure, but might be available on higher-end access points or routers.

Different subnet for different device types
I work for a website based in Europe and they pay me every month to my bank account (salary account). Every time I receive funds, I will get a call from the bank for confirmation and they ask for the source and reason. I will tell them the website name and software consultancy. They deduct some amount as charges, and credit the remaining to my account.

The question is: do I need to pay income taxes for this money I earned online?
