This is a MAC address, it's not related to the filtration process.
When did your connection problems started ?
yes it is my Mac ID (F4-6D-04-2C-5E-02) and all my laptops and pcs are connected on the same router/ Ip there fore if my miner cant mine nor i can open the site on my rig then i guess its mac ID banned or something has to be.
ohhh wait i found the problem for why it didn't connect,
NOTE: If you running miners on your rigs don't install "Malwarebytes' Anti-Malware" it blocks the site after few days, who knows why! BUT that fixed my problem

Unchecked site blocking
sorry for blaming it on your guyz ;P
After each network hop the MAC address of the current access point is not sent on to the next node, so Deepbit does not even know your MAC address until you told everyone on this forum
