A namespace in computer science (sometimes also called a name scope) is an abstract container or environment created to hold a logical grouping of unique identifiers or symbols (i.e. names). An identifier defined in a namespace is associated only with that namespace. The same identifier can be independently defined in multiple namespaces.
Network naming can be hierarchical in nature, such as the Internet's Domain Name System. Indeed, the Internet employs several universally applicable naming methods: uniform resource name (URN), uniform resource locator (URL), and uniform resource identifier (URI). Naming systems have several other characteristics.
For example, if a process has administrative permission to change the IP address of a network interface, it may do so as long as its own user namespace is the same as (or ancestor of) the user namespace that owns the network namespace. Hence, the initial user namespace has administrative control over all namespace types in the system. [11]
A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme.URNs are globally unique persistent identifiers assigned within defined namespaces so they will be available for a long period of time, even after the resource which they identify ceases to exist or becomes unavailable.

In computing, a directory service or name service maps the names of network resources to their respective network addresses.It is a shared information infrastructure for locating, managing, administering and organizing everyday items and network resources, which can include volumes, folders, files, printers, users, groups, devices, telephone numbers and other objects.
A network interface controller (NIC) is computer hardware that connects the computer to the network media and has the ability to process low-level network information. For example, the NIC may have a connector for plugging in a cable, or an aerial for wireless transmission and reception, and the associated circuitry.
In the digital age, the significance of namespace security has been magnified as the internet is predominantly navigated through the use of the Domain Name System, which constitutes a collection of namespaces, which together comprise the Internet as defined by the Internet Assigned Numbers Authority (IANA) managed DNS root zone.
Traditionally, the logical network inventory has been a separate product but in most modern systems the functionality is built in the GIS serving both the functionality of the physical network and logical network. Water network information system typically manages the water network components, such as ducts, branches, valves, hydrants ...
