Talk:Domain Name System/Draft

comment

This article is developing nicely. Thanks to those who have contributed. I think it would benefit from an overview or introduction which briefly explains what DNS is, when it was first rolled out, etc., for those who are not yet familiar with the technology. After all, DNS is a function largely hidden from many computer users who do not delve into the details of how networks are implemented, so even some savvy computer scientists might not know much about it. I appreciate what has been done so far; keep up the good work!Pat Palmer

Thanks, Pat. While I'm more a subspecialist in routing than DNS, I'm certainly comfortable with it, but for some reason, this is a painful article to write.

When you speak of the introduction, are you including some of the business and political issues, very important in absolutely current policy meetings, that are dealing with matters such as the creation of a large number of new top level domains? There is a very real collision between the original technical purpose of DNS, and business issues it was never designed to address. To some extent, there are people in business that are trying to coerce the DNS to be a search engine, which doesn't work well both from the technical and intellectual property/trademark law areas.

I think I'd put the discussion of today's politics in a special section. For the intro, I was thinking of describing, for the youngsters who might not remember, what a big innovation DNS initially was--translating raw IP addresses into user-friendly domain names, and vice versa. Also worth mentioning, I think, is how the entire internet managed to cut over to the use of DNS all at once in, was it '83? Only after describing what is is, and how important is was and is, would I go into all the technical details, the stuff that you are very expert in. This is becoming a great article; keep it up!Pat Palmer 18:46, 5 July 2008 (CDT)

Moving to closure on the "capstone" article

I don't want to put that much more into this article rather than subarticles. If things seem too detailed, let me know, but remember there should be a little introduction rather than simply linking to DNS security and the like.

Things that I didn't think needed to be here--should they be?

• Recursive versus iterative resolution
• More than a casual definition of caching
• Load sharing with tricks like round robin multiple addresses on the A record
• Any detail about subdomains, either nondelegated or delegated.

Nice intro!

Wow, nice introduction! I will try to read in detail in the next coupla days (but off to sleep tonight). This has evolved into an excellent article!Pat Palmer 21:03, 8 October 2008 (CDT)

One thought. Might you say something about resiliency? I think there's some high drama that we could mine here to make this article interesting even to those readers who are not geeks. Haven't there been some attempts to crash the name service (and thus the internet as a whole)? If I recall, there are 12 or so BIG name servers in the sky, so to speak, and though these recent attacks might have brought down a few of them, some always remained, enough to keep the net at least limping along, which was one of the key goals of its original designers. This issue (I hope I recall correctly) should be mentioned somewhere near the top of the article, perhaps in a paragraph of its own entitled "resiliency" or something or other, because it is one of the truly remarkable things about DNS that it is distributed and not centralized and so it's really not all that easy to kill the whole thing. Or so we hope (and so evidence has thus far shown). I haven't read all the article yet, so if this is already well covered, please forgive, in which case, maybe we can bubble it towards the top somehow.Pat Palmer 21:09, 8 October 2008 (CDT)
