In addition, the EUI-64 numbering system originally encompassed both MAC-48 and EUI-48 identifiers by a simple translation mechanism. The IEEE now considers MAC-48 to be an obsolete term. MAC-48 was used to address hardware interfaces within existing 802-based networking applications EUI-48 is now used for 802-based networking and is also used to identify other devices and software, for example Bluetooth. The distinction between EUI-48 and MAC-48 identifiers is in name and application only. The IEEE encourages adoption of the more plentiful EUI-64 for non-Ethernet applications. The IEEE has a target lifetime of 100 years (until 2080) for applications using EUI-48 space and restricts applications accordingly.

The IEEE manages allocation of MAC addresses, originally known as MAC-48 and which it now refers to as EUI-48 identifiers. This 48-bit address space contains potentially 2 48 (over 281 trillion) possible MAC addresses. The IEEE 802 MAC address originally comes from the Xerox Network Systems Ethernet addressing scheme. The b0 bit distinguishes multicast and unicast addressing and the b1 bit distinguishes universal and locally administered addressing. However, two NICs connected to two different networks can share the same MAC address. Network nodes with multiple network interfaces, such as routers and multilayer switches, must have a unique MAC address for each NIC in the same network. MAC addresses are formed according to the principles of two numbering spaces based on Extended Unique Identifiers (EUI) managed by the Institute of Electrical and Electronics Engineers (IEEE): EUI-48-which replaces the obsolete term MAC-48-and EUI-64. The address typically includes a manufacturer's organizationally unique identifier (OUI). Many network interfaces, however, support changing their MAC address. Each address can be stored in hardware, such as the card's read-only memory, or by a firmware mechanism. MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Universal Table Browser can run against large databases (over 10,000 tables) and MASSIVE tables (over 100 million rows), especially mainframes and mini systems.Label of a UMTS router with MAC addresses for LAN and WLAN modulesĪ media access control address ( MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. It is used on a daily basis against large, varied and "real" databases. It has been developed out of frustration with the inadequacies of existing tools. The Universal Table Browser has been extensively proven on the road as an effective query tool.
#Universal database table address professional
It gives sufficient functionality for ANY database professional or end user to build and execute SQL queries against their databases. It is a simple to use, super efficient query tool. It is a technically superior product and performs exceptionally well against all databases, from the smallest Access database to the largest enterprise system. During product demos we've seen people fall off their chairs at the speed (honest). Universal Table Browser is stable and super fast. The browser has been optimized for MASSIVE databases, capable of dealing with MILLIONS of rows and thousands of columns and is capable of delivering data to you at blistering speed, the likes of which you've never seen before. A well designed graphical user interface means that you can simply point and click your way to complex SQL statements or use the SQL editor to write your own query. Universal Table Browser is a fully functioning Query Tool giving you access to ANY database using ODBC.
