Nmap sends out individual signals to each IP address and waits for a reply. As replies return, Nmap compiles them into a database to keep track of responses, a process that slows down the scanning process. In contrast, ZMap uses cyclic multiplicative groups, which allows ZMap to scan the same space roughly 1,300 times faster than Nmap. [6]
Pi-hole is a Linux network-level advertisement and Internet tracker blocking application [3] [4] which acts as a DNS sinkhole [5] and optionally a DHCP server, intended for use on a private network. [1] It is designed for low-power embedded devices with network capability, such as the Raspberry Pi, [3] [6] but can be installed on almost any ...

Some commercial databases have augmented geolocation software with demographic data to enable demographic-type targeting using IP address data. The primary source for IP address data is the regional Internet registries which allocates and distributes IP addresses amongst organizations located in their respective service regions:
arpwatch is a computer software tool for monitoring Address Resolution Protocol traffic on a computer network. [1] It generates a log of observed pairing of IP addresses with MAC addresses along with a timestamp when the pairing appeared on the network. It also has the option of sending an email to an administrator when a pairing changes or is ...
A Domain Name System blocklist, Domain Name System-based blackhole list, Domain Name System blacklist (DNSBL) or real-time blackhole list (RBL) is a service for operation of mail servers to perform a check via a Domain Name System (DNS) query whether a sending host's IP address is blacklisted for email spam.

To solve this problem, QUIC includes a connection identifier to uniquely identify the connection to the server regardless of source. This allows the connection to be re-established simply by sending a packet, which always contains this ID, as the original connection ID will still be valid even if the user's IP address changes. [28]
