The ipconfig command supports the command-line switch /all. This results in more detailed information than ipconfig alone. An important additional feature of ipconfig is to force refreshing of the DHCP IP address of the host computer to request a different IP address. This is done using two commands in sequence.
Unix-like operating systems commonly implement IP address blocking using a TCP wrapper, configured by host access control files /etc/hosts.deny and /etc/hosts.allow.. Both companies and schools offering remote user access use Linux programs such as DenyHosts or Fail2ban for protection from unauthorized access while allowing permitted remote access.
COMMAND: The command to run (add, delete, change, get, monitor, flush)-net: <dest> is a network address-host: <dest> is host name or address (default)-netmask: the mask of the route <dest>: IP address or host name of the destination <gateway>: IP address or host name of the next-hop router
The cd command can be used to change the working directory of the working drive or another lettered drive. Typing the drive letter as a command on its own changes the working drive, e.g. C: ; alternatively, cd with the /d switch may be used to change the working drive and that drive's working directory in one step.
(Left) command-option-* triggers a non-catchable hardware reset thereby hard rebooting the computer. (Contrary to Ctrl+Alt+Del on a PC compatible computer which triggers only a software reset.) On the NeXT ADB keyboard, the Command keys were replaced by keys labeled help and the Command key morphed into a wide Command bar in front of the space ...
The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0 / 16 (169.254.0.0 – 169.254.255.255) for link-local addressing. [1] The entire range may be used for this purpose, except for the first 256 and last 256 addresses (169.254.0.0 / 24 and 169.254.255.0 / 24), which are reserved for future use and must not be selected by a host using this dynamic ...
IP addresses are assigned to a host either dynamically as they join the network, or persistently by configuration of the host hardware or software. Persistent configuration is also known as using a static IP address. In contrast, when a computer's IP address is assigned each time it restarts, this is known as using a dynamic IP address.
