ICANN Internet Corporation of Assigned Names and Numbers - a non-profit private corporation
based in Los Angeles U.S.A.
Functions as the IANA — Internet Assigned Numbers Authority — previously run by
Click here for its early history, first at UCLA then USC.
Responsible for the allocation of IPv4 addresses 0.0.0.0 to 255.255.255.255 via five Regional Internet Registries (RIRs).
On Feb 3rd 2011, this free pool of IPv4 address space was depleted.

IANA also oversees a small root zone file of IP addresses for the registries of the *1446 Top Level Domains (TLDs) .com, .uk, .au, .cn etc which it publishes on thirteen
Asia Pacific Regional Internet Registry | .au TLD Name registry for Australia, and generic .com and .net TLD Name registries based in the US | |

APNIC - Asia Pacific Network Information Centre based in South Brisbane. As of April 14th 2011, all of its IPv4 address space was allocated. While fragments are still being recovered and reissued, IPv6 (with 128 bit addressing) is seen by IANA as the future. Click here for more details. Previously with IPv4 (32 bit addressing) it would receive allocations in blocks of 16 million addresses which it reallocated in smaller blocks of, say, 64000 addresses to ISP's - Internet Service Providers e.g. Telstra, Optus, iiNet, iPrimus, TPG, etc. The ISP's then allocate individual addresses, e.g. 202.139.83.152, to each computer, as required. Within APNIC there are also seven National Internet Registries (NIRs) in Japan, China, Taiwan, Korea, Indonesia, Vietnam and India. | .auDA: is the Australian Government endorsed body that administers the .au domain space. In July 2018 they appointed US-based body Afilias to supply its registry services which includes publishing the file of server addresses for all the .au domains. E.g. swcs.com.au which is currently located on the Quadra Hosting network. The domain's manager (Stephen Williamson) keeps Afilias updated through his registrar with any changes to the IP addresses of the swcs.com.au name servers. Whenever the host is located via a name server, your ISP caches (remembers) its name and its IP address for, say, 24 hours, then deletes the record automatically. The cache reduces Internet traffic, and the automatic deletion (which means that the next time the name is requested, the ISP has to look it up again), enables a domain to change server hosts with only a 24 hour time delay for most ISP's to be updated. Your PC saves a copy of the actual page in its cache, downloading a fresh copy only after a certain period of time, or when the user presses the refresh button. | Verisign: is the organization which actually maintains the root zone file, administers two root servers and supplies registry services for the generic .com and .net domains including google.com and microsoft.com
Google and other Search Engines store words and phrases, associating them with unique domain / page names. They do this by simply following the hyperlinks within the web pages they know about, thus discovering new ones, and are thus building and refreshing the information in their databases continually. Also, thus, when they display a search result, it may be a somewhat "stale" copy of the page. When you click on the link to download it, you then see the latest copy. |
Although Google's statistics show penetration of IPv6 is increasing with the USA currently on 52%, there is still high use of IPv4 addresses worldwide. China's figures show just 5% are using IPv6, well, they do have 350 million IPv4 numbers available to their network.
In other countries in the Asia Pacific region, Australia's current IPv6 usage is 30%, Japan is at 53%, and India is 73%. Click here to see these stats. Click here to see your IPv6 & IPv4 address.
* Examples of Top Level Domain Registries: .com=160million (administered by Verisign),
Note, the latest Domain Name Industry Brief says that 2022 ended with 350 million registrations across all TLDs, substantially fewer than the 367.3 million it reported at the end of the third quarter in 2021. Verisign no longer counts the six Pacific and African ccTLDs managed by Freenom, notably .tk, which had contributed 24.7 million names to the Q3 2021 tally.
The report says: "the .tk, .cf, .ga, .gq and .ml ccTLDs have been excluded from all applicable calculations, due to an unexplained change in estimates for the .tk zone size and lack of verification from the registry operator for these TLDs."

Great seeing John, Tim, and Dave at Maccas after prayer and fellowship with Kingsley at the Church.
Guys, I’ve just updated my standard web page for smartphones (as well as PCs), very fast link, click on Christian Books and Media, and it’ll take you straight to an “etymologies” link, alphabetically sorted. Click on the image file below, you’ll see what I mean. Just added that work I spent “hours” on earlier this week on “book of judges” and “jubilee years”.
No video advertisements, hopefully fast response even on mobile coverage.
Talking about smartphones and mobile coverage outside Brisbane/Sydney/Melbourne/Perth, further to John and Tim’s comments at Maccas, Whirlpool have a chat-page on this that has been running for two-three years. I looked through it, it’s long, but it has some good background.
The big issue with the Internet of course is there is no centralised network, if a packet of your data file, say 1500 bytes, isn’t acknowledged within say, one second, uploading or downloading over TCP/IP, the packet is simply resent at set intervals until it either gets through or you give up. With multi-megabyte image files, advertisements, movies, and hundreds of mobile users trying to grasp some small slice of radio spectrum on the same base station, you get noise db problems, and continual automatic resending, and it just compounds the issue. Hmmm, yes, poor Telstra.
With ADSL, at least you get a dedicated line as an individual user, though the telephone line quality at times is poor. Television coax cable is of course the best, it has 1000 times the spectrum of telephone cable, you may be sharing the spectrum with up to 200 other users simultaneously, but generally it’s pretty fast and good.
But getting back to that article above — it started in 2011 with a fair few queries/complaints, it’s a long article and still going, it hit a bit of a climax mid-last year with Telstra’s new, portable, smart antennas (boosting signals inside buildings) — you can pay them off at a good monthly rate. See the comments by bransby1 in this extract from the page.

I do deeply remember back in 1983-1984, the Apple Lisa / Macintosh debacle, especially with NASA, no, they were not impressed after all the investment / infrastructure that they put in place with the Lisa. I imagine a few heads rolled. Here’s the article in Wikipedia.
https://en.wikipedia.org /wiki/Apple_Lisa#Reception
I often wonder if Apple management got a bit shirty with Steve Jobs, with what they must have copped from NASA, with the much cheaper Macintosh coming out a year later, and using different software. Because he left in 1985, then brought out the NeXT computer, which then became the computer used when Tim Berners-Lee developed HTML1 at CERN in Geneva in 1989. A language that not only "wrote" pages, but could also "read back" your queries, providing a simple search mechanism. Click here re HTML's launch in the US in 1991-92 — on another NeXT computer — and how it then "took off".
The thing about the HTML rules that are in its markup language, they’re completely free to learn, they’re very, very simple (I think), you don’t need to buy Adobe Acrobat to set out the document like you generally do if generating a PDF, you can use Notepad, it’s fine and it’s free, and importantly, every browser on the market supports all the main markup rules that came out in HTML1 through to HTML5. Twenty-five years later.
Some of the older versions of current browsers (pre 2010) only support the rules up to HTML4 ( which came out in 1997).
HTML5, yes, is discouraging the use of certain "internal" table markup rules, recommending new "external" stylesheet rules instead, due to the limited width in screen space on smartphones.
But the literally billions of web pages, so many electronic documents, out there being picked up by Google, no browser is currently not endeavouring to do the best it can on smartphones with those tables, because some of those documents may be pretty valuable to look at, and may not be, may never be changed.
Interesting. Steve
