Note that the new syntax differs significantly from that of iptables, in which the same rule would be written: iptables -A OUTPUT -d 1.2.3.4 -j DROP The new syntax can appear more verbose, but it is also far more flexible. nftables incorporates advanced data structures such as dictionaries, maps and concatenations that do not exist with ...

iptables is a user-space utility program that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall, implemented as different Netfilter modules. The filters are organized in a set of tables, which contain chains of rules for how to treat network traffic packets.
Netfilter is a framework provided by the Linux kernel that allows various networking-related operations to be implemented in the form of customized handlers.Netfilter offers various functions and operations for packet filtering, network address translation, and port translation, which provide the functionality required for directing packets through a network and prohibiting packets from ...
tc relates to the Linux kernel packet scheduler as iptables to netfilter. Both are user-space CLI programs that are used to configure their respective Linux kernel subsystem. tc (traffic control) is the user-space system administration utility program used to configure the Linux kernel packet scheduler.
A black hole IP address specifies a host machine that is not running or an address to which no host has been assigned. [1]Even though TCP/IP provides a means of communicating the delivery failure back to the sender via ICMP, traffic destined for such addresses is often just dropped.
Tail drop is a simple queue management algorithm used by network schedulers in network equipment to decide when to drop packets.With tail drop, when the queue is filled to its maximum capacity, the newly arriving packets are dropped until the queue has enough room to accept incoming traffic.
Random early detection (RED), also known as random early discard or random early drop, is a queuing discipline for a network scheduler suited for congestion avoidance. [1]In the conventional tail drop algorithm, a router or other network component buffers as many packets as it can, and simply drops the ones it cannot buffer.
