        Then there is basically no inter-As anycast besides the anycast prefix for DNS root, since I only noticed like 8 prefixes that are announced by more than 3 ASes..
...but inter-domain anycast is often achieved by using a single origin AS, which is then transited through the 'provider' autonomous systems. In which case, you may be looking for the wrong thing. Rob
