Many ISPs name servers cache their records. Even if you turn down your TTLs, not all ISPs (especially the large ones) will respect them. They will cache based on their settings. The end problem is that when you have a failure, your DNS switches over to point at your secondary VoIP server, but your clients all over the world still end up getting the old DNS info from their ISP and try and contact the dead server. ----- Original Message ----- From: "Duane" <[EMAIL PROTECTED]> To: "Blaine Aldridge" <[EMAIL PROTECTED]> Cc: <[email protected]> Sent: Monday, May 21, 2007 7:28 PM Subject: Re: [on-asterisk] Creating an Asterisk Failover solution > Blaine Aldridge wrote: >> Leif, >> >> Can I take one publicly routable IP address from a /24 and then just >> bind it on a completely different network / ASN? >> >> I understand how to do it on the same network but I'm not sure if you >> can do this over different ASN's. > > SRV records would be the cheaper options otherwise you will need one or > more dedicated load balancing boxes of some description. > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
