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:
“Adultery is the vice of equivocation.
It is not marriage but a mockery of it, a merging that mixes love and dread together like jackstraws. There is no understanding of contentment in adultery.... You belong to each other in what together you’ve made of a third identity that almost immediately cancels your own. There is a law in art that proves it. Two colors are proven complimentary only when forming that most desolate of all colors—neutral gray.”
—Alexander Theroux (b. 1940)
“The essence of the modern state is that the universal be bound up with the complete freedom of its particular members and with private well-being, that thus the interests of family and civil society must concentrate themselves on the state.... It is only when both these moments subsist in their strength that the state can be regarded as articulated and genuinely organized.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“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)
