GeoLite Legacy builds

Updated versions of the GeoLite Legacy databases are now only available to redistribution license customers,

although anyone can continue to download the March 2018 GeoLite Legacy builds.

Starting January 2, 2019, the last build will be removed from our website.

GeoLite Legacy database users will need to switch to the GeoLite2 or commercial GeoIP databases and update their integrations by January 2, 2019.

Mininet is a VM, also a great way to develop, share, and experiment with OpenFlow and Software-Defined Networking systems.

containers (network namespace)
Note that only the network is virtualized;
each host process sees the same set of processes

i.e.

mininet> h1 ps -a
mininet> s1 ps -a

By default, the hosts are put in their own namespace, while switches and the controller are in the root namespace.
