As I have necessary tools to quicly filter such data from multiple DBs, you might be interested in the list of those self-reporting anycast in RR (its not very long):
184.108.40.206/24 AS3557 - ISC F ROOT (source: OTTIX, VERIO, RIPE)
220.127.116.11/24 AS24246 - INTERNAP (source: SAVVIS, RADB)
18.104.22.168/22 AS32476 - Tellme Networks (source: RADB)
22.214.171.124/24 AS27598 - IS.CO.ZA (source: RADB, RIPE)
126.96.36.199/24 AS29117 - irc-hispano.org (source: RIPE)
188.8.131.52/24 AS12859 - BIT.NL 6to4 relay RFC3068 (source: RIPE)
184.108.40.206/24 AS33837 - PRQ.SE (source: RIPE)
220.127.116.11/24 AS31529 - DENIC (source: RIPE)
18.104.22.168/24 AS12654 - RIPE NCC RIS (source: RIPE)
22.214.171.124/24 AS12654 - RIPE NCC RIS (source: RIPE)
126.96.36.199/24 AS3344 - kewlio.net 6to4 relay RFC3068 (source: RIPE)
2001::500::/48 AS3557 - ISC F ROOT (source: RIPE)
2002::/16 AS3344 - 6to4 relay anycast - no longer done, right??
Getting back to the subject of anycast DNS TLDs, its possible that above
did provide a clue that one of the .ZA servers might be anycasted (although
NSZA.IS.CO.ZA is 188.8.131.52 right now and not listed anycast in RR).
P.S. I will search for anycast in description of ip whois data when I get
a chance and if its not long and interesting may post summary here as well.
