Once upon a time, Patrick W. Gilmore <patrick@ianai.net> said:
* How many applications are even aware multiple addresses were returned?
Most anything that supports IPv6 should handle this correctly, since getaddrinfo() will return a list of addresses to try.
* How do you guarantee sub-second failover when most apps will wait longer than one second to see if an address responds?
That's a bigger issue. Also, for web services, the application might wait, but the end-user usually won't (if the site doesn't come up in a second, they move on to the something else). -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
