Anycast is an Internet addressing method in which many servers announce the same IP address and routing delivers each packet to the nearest one.
CIDR, or Classless Inter-Domain Routing, describes IP address blocks with variable-length prefixes such as /24 and lets routers aggregate routes efficiently.
IPv4 is version 4 of the Internet Protocol, which identifies hosts with 32-bit addresses and routes packets between networks across the Internet.
IPv6 is the 128-bit version of the Internet Protocol that gives every device a globally unique address and replaces the exhausted IPv4 space.
NAT (network address translation) rewrites IP addresses and ports as packets cross a router, letting many private hosts share one public address.
A private IP is an address from ranges reserved for internal networks, reusable by any organization and not routed on the public Internet.
A public IP is a globally unique, routable Internet address assigned through the registry system and reachable from any network on the Internet.
