Origin of reverse lookup

[alcol alcol]

Ohuuuuuuuuuu I haven't written slave but was not your email
if you want to say something don't quote others taht say right things
if I don't use words as you could use or like is not your matter

as last part of your reply, please think to yourself as you started to quote me with no meaning saying same things as me



Why do you look at the speck that is in your brother's eye and don't notice the beam that is in your eye?

don't get me wrong but when you know that little about DNS that you
expect a service on the internet cares about what you configured at your
local box you shouldn't be that arrogant!
