It's a reasonable way to perform certain kinds of replication. DDNS can often converge faster than BGP, but this *requires* that clients observe TTLs. Many do not. I don't know about current browsers, but not too long ago browsers would keep the results of a DNS lookup until they died.
We offer a replication service (as a special) based on BGP. We do not recommend it unless the DDNS approach will not meet requirements. And then we work to find alternatives! To do it yourself is rather simple (Catbert's grin here.) First. Find a collection of ISPs that will agree to accept your BGP4 announcements of this foreign (to all save perhaps one ISP) AS. Oh, get an AS #. Then get someone to assign you some address space that can be so advertised. If you're lucky you have a spare /19 in your back pocket. :) After that it's *easy*. OK, I'm being cute. Some large ISPs will work with you to do this wholly in their diverse facilities with private AS numbers and address space they have reserved for this. AFAIK, the last free version of gated will work for IPv4 versions of this approach. And that runs on FreeBSD. -sam _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
