  DNS performance goes to hell... to fight spam?

A couple internet veterans griped at me today:The world's most distributed database is breaking down, because people are afraid to cache anything... and we're still not using good crypto. It's SPF, says one... Self centered stupidity says another:

It's the collapse of the commons! sez a third... The internet. No one owns it. Everybody can use it. "Everyone can improve it".

Although I gain clarity in my DNS files by using CNAME chains, I cause two or three DNS lookups for every access to my web site and mail server. The packet overhead isn't much, but the added latency does add up. Note to self - REFORM! do a global search and replace on my DNS records so I return to a 1 to 1 match between IP and name... And:

Big sites using a TTL of 0 completely thwarts the intent of the several million DNS caches on the internet, to what end? There are far better load balancing solutions. If millions of sites set TTL to 0, the Net would collapse....
 
Comments:
Alot of interesting comments on this blog, I was searching for some doctor related info and some how cam across this site. I found it pretty cool, so I bookmarked. I'll really liked the second post on the front page, that got my attention.

My site is in a bit different area, but just as useful. I have a mens male enhancement reviews related site focusing on mens male enhancement reviews and mens health related topics.
