WireGuard is designed to be extended by third-party programs and scripts. This has been used to augment WireGuard with various features including more user-friendly management interfaces (including easier setting up of keys), logging, dynamic firewall updates, dynamic IP assignment, [15] and LDAP integration.

Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
ipconfig in Mac OS X serves as a wrapper to the IPConfiguration agent, and can be used to control the Bootstrap Protocol and DHCP client from the command-line interface. [8] For example, you can release and renew an IP address if it happened to be assigned incorrectly by the DHCP server during the automated assignment process. [9]
This message may contain the client's Client ID (Option 61, containing a unique value, traditionally a MAC address), the IP address that the server is offering, the subnet mask, the lease duration, and the IP address of the DHCP server making the offer. The DHCP server may also take notice of the hardware-level MAC address (as specified in the ...
A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. [1] In this attack, a host sends hundreds of ping requests with a packet size that is large or illegal to another host to try to take it offline or to keep it preoccupied responding with ICMP Echo replies.
The IP header is not included. Identifier: 16 bits Can be used by the client to match the reply with the request that caused the reply. Sequence number: 16 bits Can be used by the client to match the reply with the request that caused the reply. Payload: variable length Optional.
The pseudo-header consists of the source IP address, the destination IP address, the protocol number for the TCP protocol (6) and the length of the TCP headers and payload (in bytes). Urgent Pointer: 16 bits If the URG flag is set, then this 16-bit field is an offset from the sequence number indicating the last urgent data byte.
In computing, a ping sweep is a method that can establish a range of IP addresses which map to live hosts. The classic tool used for ping sweeps is fping, [ 1 ] [ 2 ] [ 3 ] which traditionally was accompanied by gping to generate the list of hosts for large subnets, [ 4 ] although more recent versions of fping include that functionality.
