DNS parking may be required in the future. A few days ago Sedo informed its customers that its primary advertising provider (read: Google) may change the way it allows domains to be parked. URL forwarding will be out and all domains will need to be parked using DNS. This change has been rumored for a while and likely has to do with tighter control and transparency for parked domains, as well as changes to how parked ads are served technically.

According to the communication from Sedo:

Based on current discussions it is possible that our ad provider will cease its provision of advertising to URL-parked pages and in consequence only support DNS parked domains.

This step is considered by the online advertising provider in response to advertiser feedback and would affect all URL-parking customers at all parking companies worldwide that share this advertising provider. This change could happen in the near future (potentially as early as the fourth quarter of 2010) and we wanted you to have this information in advance to take into account for your internal planning.

If you already have your domains parked with a particular companies nameservers such as ns1.sedoparking.com, this won’t affect you.

I think we all saw this one coming but its probably for the best anyway. URL forwarding is a lot less reliable than changing the NS and you also get to wild card more of your traffic this way so it should result in more earnings.

Im surprised Sedo didnt mention these things....

When it'll be . Kindly inform me as soon as possible.
