Nmap can provide further information on targets, including reverse DNS names, device types, and MAC addresses. [13] Typical uses of Nmap: Auditing the security of a device or firewall by identifying the network connections which can be made to, or through it. [14] Identifying open ports on a target host in preparation for auditing. [15]
A fast-flux service network (FFSN) is a network infrastructure resultant of the fast-fluxed network of compromised hosts; the technique is also used by legitimate service providers such as content distribution networks (CDNs) where the dynamic IP address is converted to match the domain name of the internet host, usually for the purpose of load balancing using round-robin domain name system ...
Starting 1991-06-01, was used to map Public Data Network addresses to IP addresses. Returned to IANA 2008-01-22. This network was reclaimed by IANA in 2007 and was subsequently re-allocated in 2010. See RFC 877 and RFC 1356 for historical information. [10] 15.0.0.0/8 ARIN: 1991-09
Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.

Network address translation between a private network and the Internet. Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [1]
Each 1-bit denotes a bit of the address range which must remain identical to the given IP address. The IP address in CIDR notation is always represented according to the standards for IPv4 or IPv6. The address may denote a specific interface address (including a host identifier, such as 10.0.0.1 / 8), or it may be the beginning address of an ...
IPv6 hosts may automatically generate IP addresses internally using stateless address autoconfiguration (SLAAC), or they may be assigned configuration data with DHCPv6, or both. IPv6 hosts that use stateless autoconfiguration may need information other than what SLAAC provides on a given network.
