moved site. new sites resolving to old host

Man. I like, have never found my answer in the help pages before getting to this point.

Okay. I've moved my multisite from oldhost.com to mynewhost.com.

When I <create new site> from the Dashboard, the new sites are resolving to newsite.oldhost.com instead of what I want, which is newsite.mynewhost.com

what's happening? I've asked my registrar to point the A name servers towards the new position. * and * the *.mydomain for new sites wildcard.

Help?
