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:
“You hear a lot of dialogue on the death of the American family. Families aren’t dying. They’re merging into big conglomerates.”
—Erma Bombeck (b. 1927)
“Whatever else American thinkers do, they psychologize, often brilliantly. The trouble is that psychology only takes us so far. The new interest in families has its merits, but it will have done us all a disservice if it turns us away from public issues to private matters. A vision of things that has no room for the inner life is bankrupt, but a psychology without social analysis or politics is both powerless and very lonely.”
—Joseph Featherstone (20th century)
“The great networks are there to prove that ideas can be canned like spaghetti. If everything ends up by tasting like everything else, is that not the evidence that it has been properly cooked?”
—Frederic Raphael (b. 1931)
