I was wondering if anyone had recommendations on IPv4 Anycast resources
(whitepapers, RFCs) as it relates to DNS?

Thanks in advance.

I found the following useful:

    http://ftp.isc.org/isc/pubs/tn/isc-tn-2004-1.html
    http://www.linuxsa.org.au/meetings/2006-07/anycast-dns.pdf

They're getting a bit dated, but still OK.

If you're interested in looking at it from a campus/enterprise point
of view, we recently reworked our DNS/Anycast setup, and here are the
deployment notes:

(you can stop reading at section 4, where it gets into the specifics
of our homebrew IPAM system). In a nutshell, we're using the "ip sla"
feature on our Cisco boxes to conditionally announce host routes for
the published anycast IPs from several places in our network
(subsection 2.4 in the document).
