Aristotle and everyone,
My apologies for posting to the wrong list. My idea was that writing a
DNS server that can return anything (no silly "zone files") was to buy
a domain (let's say "ktjones.com) and set it up to do the following:
1. Have fortune.ktjones.com return a random fortune (TXT record with a
TTL of 1 second, though most nameservers will cache it for longer)
2. Have mirror.ktjones.com return the IP address of the requestor (so
you can see where your DNS queries *really* go)
3. Have time.ktjones.com return the current time (either as a TXT
record or the result of Perl's time() converted to IP address format)
w/ a TTL of 1 second-- see how long your DNS server caches 1 second TTLs.
4. Have ttl-[n].time.ktjones.com do the same thing but with a TTL of n seconds.
5. Have http.url.with.slashes.replaced.by.dots.ktjones.com return (TXT
record) the contents of a specified URL, perhaps adding a "part[n]"
parameter if TXT record size is limited. Added bonuses:
5a. Quasi-anonymizes web access (almost everyone proxies DNS
requests, and it's UDP)
5b. Caches web content on nameservers -- content from more popular
webservers will be available on multiple nameservers, even if the
site itself goes down
5c. UDP more efficient than TCP?
5d. Pollutes the DNS namespace :)
6. Scaled-down version of above (limited size TXT records):
6a. "stocksymbol.stock.ktjones.com" return a stock quote
6b. "metarsymbol.metar.ktjones.com" return the latest METAR (weather) for
a given METAR code
6c. "content.email-address.email.ktjones.com" sends an email to
someone (yeah, this could admittedly be abused)
6d. "content.(screename|phonenumber).(aim|sms).ktjones.com" could
send an AIM message or SMS to someone
I guess I should've posted to fun-with-DNS, but I don't think that exists!

Hmm. Your question is not very Fun, so this is the wrong list to
ask. You probably want to take this to Perlmonks.
