Merging Private Networks
Since the private IPv4 address space is relatively small, many private IPv4 networks use the same address space. This creates a common problem when merging such networks, namely the duplication of addresses on multiple devices. In this case, networks or hosts must be renumbered, often a time-consuming task, or a network address translator must be placed between the networks to masquerade the duplicated addresses.
To mitigate this problem for IPv6, RFC 4193 specifies a large (40-bit) unique Global ID to be pseudo-randomly generated by each organization using Unique Global Addresses. It is very unlikely that two network addresses generated in this way will be the same.

Famous quotes containing the words merging, private and/or networks:
“An administrator in a bureaucratic world is a man who can feel big by merging his non-entity in an abstraction. A real person in touch with real things inspires terror in him.”
—Marshall McLuhan (1911–1980)
“That’s interesting. Sort of a private preserve for teenagers, huh? I suppose as adults we’re lucky to find a parking space.”
—Kenneth Langtry. Herbert L. Strock. Prof. Frankenstein (Whit Bissell)
“To be perfectly, brutally honest, those of us who are still carrying diaper everywhere we go are not at our most scintillating time of life....We need to remember that at one time in our lives, we all had senses of humor and knew things that were going on in the world. And if we just keep our social networks open, there will be people ready to listen when we once again have intelligent things to say.”
—Louise Lague (20th century)
