Originally, the Network Information Center (NIC) was the central office for the globally coordinated allocation of IP addresses and domain names. The NIC manages the top-level domains (TLD) such as .org, .edu, .mil, .gov of the Internet. Today there are many NICs operated by local, regional and national networks around the world. In Germany it is the DeNIC.
The individual NICs offer user support, training, document services and much more.
