Object

column r/w OctetString 
Each bit of this value set to '1' indicates a specific requested DHCP option (Bitmap
of 255 options represented by 32Bytes).
When the bit is set to '1' then specific DHCP option is requested by the client. 
Subnet mask bit 1 - is always requested.
              
Bits are numbered from the most-significant leftmost bit in the
octet (bit 0) to the least-significant rightmost bit (bit 7).
              
Numbering continues across octets, so that octet 1 bit 0 is
called bit 8.  
              
Default: '0x5201' which equals to:
bit 1 - Subnet mask (Always requested!)
Bit 3 - Default routers
Bit 6 - DNS servers
Bit 15 - Domain Name
