I noticed on my domain dns zone I keep having machines populated with IP's of 192.168.1.x, hundreds of them. At our office we all have laptops that we take home and bring in to the office (we have no desktops at the office for employees). We don't use 192.168.x.x at all anywhere on our network we use 10.x.x.x. subnets. Why am I seeing tons of HOST A records for users laptops with 192 addresses? I delete them and new ones come back!
How can I prevent this from being populated in my dns forward lookup zone?
