Outsourcing my DNS lookup service to OpenDNS

DNS subsystem is a real headache to manage. You will realize that once you have to tweak the system, especially if you want to incorporate your own filtering/access-blocking rules.

And the DNS Cache Poisoning. It's a real threat.

While I believe my DNS subsystem is quite safe under the good-old djbdns servers, I am now testing the OpenDNS, a DNS cache service provider. One of the good things about OpenDNS is that they even allow a single-IPv4 address network to be individually managed, even it's dynamically allocated, as in most of the cases for non-static-IPv4 users.

If you can trust your ISP for the DNS management, you are on your own. But if you can't or don't, OpenDNS is a good alternative. I notice many ISPs still have not changed their DNS cache servers to prevent the poisoning attack as of today (July 24, 2008); using OpenDNS from such a mobile networking environment will make the whole DNS access much secure.

My allegation of spamdexing is finally dropped

It seems that the Blogger admin finally dropped the allegation of spamdexing from http://macrofield.blogspot.com/. It took more than 2 months, but less than 3 months, to solve this issue.

Of course, I removed the suspicious META refresh tag from the alleged page.
