NetLookup is a service aimed towards computer networking professionals. The goal is to provide an easy interface to a multitude of different databases, presenting the data in a format that is fast to read.
To use the service, simply input the query in the field above. The search engine will automatically understand what kind of data it is and do a proper search based on the input.
Queries formatted as a MAC address will be treated as such. If it looks like an IP (both IPv4 and IPv6), all data will be fetched from the appropriate RIR. Finally, if it's a domain name all registrant data will be fetched from the registrar.
By using the field above you can find a MAC address vendor using an MAC address. You only need the first 6 first chars to make a search, those are the vendor specific chars. NetLookup supports all known formats of an MAC address, so you just enter the MAC address from your application into the searchfield to make a lookup.
Other formats are also available, see the list below.
All MAC adress vendors are listed in tableform at this page.
