What does a Wide IP Zone look like

thanks George for the quick response .. I've read some deployment guides and basically understandthe mechanism you mentioned.. However, as I don't have access to a real thing (GTM), some part still not very sure :-). So you mean if I create a Wide IP, www.wip.example.com, it would not be a zone created, wip.example.com, with a physical/electronic zone file? However, if I do a zone transfer, what should be in that zone? Would there be an A record mapping to the load balanced IP, besides the SOA, NS, and server A record (GTM listener IP)? Heard a lot about the wideip.conf file, if a wide IP www.wip.example.com created, what a typical wideip.conf would look like then? Thanks again George!
