[Chapter-delegates] Seeking Views: DNS Filtering

[Ang Peng Hwa (Prof)]

Dear Sally,

Minor technical point in the first row of the table:
Easily
Circumvented: Users who wish to download filtered content can simply use IP addresses instead of DNS names.

To prevent the user from using the IP address, a mechanism must be installed so that the IP address is looked up and then blocked. But this adds to cost and delays the response time.

Regards,
Peng Hwa ANG

Subject: [Chapter-delegates] Seeking Views: DNS Filtering

Dear ISOC Chapter Colleagues,

As you may be aware, efforts to address illegal online activities using DNS filtering techniques have been cropping up all over the globe.  Attached is a DRAFT ISOC paper that outlines the issue and offers ISOC's concerns with this approach.  This paper is aimed at a non-technical audience.

We want to share this draft paper with you and seek your views on its content.  Because this paper will help inform an IGF Workshop in September, we would appreciate if you could send us any comments as soon as possible but not later than FRIDAY, 09 SEPTEMBER.  This way, we will have time to consider all the views as we put together a final version.

Thanks in advance!

Sally Wentworth
Andrei Robachevsky
