Explanation:
If L(D1) = L(D2), the D has every state being final
If L(D1) = L¯(D2), the D has every state being final
If L(D1) = ∅, then L(D) = L(D2).
If L(D1)=Σ, L(D) = L(D2)

If 29 bits of the 32 available addressing bits are used for the subnet, then only 3 bits giving 2^3=8 combinations remain for the host addresses. 
In reality, the all zeros and all ones addresses are reserved. So, 8 addresses can exist, but 6 of those are available.

- By disabling the URL from the function of file handling that basically accept the local file as the parameters but it also accept the URL.  It can even now get to outer destinations by utilizing fsockopen or any of the CURL capacities. 
- The safe mode  of PHP is presumably probably the best alternative to secure your server however it very well may be prohibitive. Whenever initiated, experimental mode averts access to records not claimed by Apache and access to condition factors and execution of double projects are likewise debilitated.
