How IPv6 Works and architecture |
|
Internet Protocol version 6 (IPv6) is a networking protocol that allows Windows users to communicate with other users over the Internet. It interacts with Windows naming services such as Domain Name System (DNS) and uses security technologies such as Internet Protocol security (IPSec), because they help facilitate the successful and secure transfer of IP packets between computers.
Ideally, IPv6 is used in a pure environment, that is, an environment where IPv6 is the exclusive Internet protocol used between computers. Currently, however, pure IPv6 transmissions are attainable only with routers that support IPv6 and computers that are running Windows and that support IPv6. As IPv6 supplants IPv4, pure IPv6 across the Internet will become more prevalent and will eventually replace IPv4. Until that occurs, the transition technologies described in this reference can be used to bridge the technological gap between IPv4 and IPv6. |

Google Search Tips |
|
Here are some search syntax basics and advanced tricks for Google.com. You might know most of these, but if you spot a new one, it may come in handy in future searches.
| 
|
• A quote/ phrase search can be written with both quotations ["like this"] as well as a minus in-between words, [like-this].
• Google didn’t always understand certain special characters like [#], but now they do; a search for [C#], for example, yields meaningful results (a few years ago, it didn’t). This doesn’t mean you can use just any character; e.g. entering [t.] and [t-] and [t^] will always return the same results.
• Google allows 32 words within the search query (some years ago, only up to 10 were used, and Google ignored subsequent words). You rarely will need so many words in a single query – [just thinking of such a long query is a hard thing to do, as this query with twenty words shows] – however, it can come in handy for advanced searching... especially as a developer using the Google API.
• You can find synonyms of words. E.g. when you search for [house] but you want to find “home” too, search for [~house]. To get to know which synonyms the Google database stores for individual words, simply use the minus operator to exclude synonym after synonym (they will always show as bold in the SERPs, the search engine result pages). Like this: [~house -house -home -housing -floor].
• To see a really large page-count (possibly, the Google index size, though one can only speculate about that), search for [* *].
• Google has a lesser known “numrange” operator which can be helpful. Using e.g. [2000..2005] (that’s two dots inbetween two numbers) will find 2000, 2001, 2002 and so on until 2005. |
