[NTLUG:Discuss] How long are MAC addresses cached?

[Neil Aggarwal]

Hello:

I moved an IP address to a different server than it
was previously on.

I can load view the website on that IP from another 
server connected to the same switch as the new server, 
but I can't view the website from my laptop connected
via my ISP's wireless connection.

I assume that is happening because the core routers
are still using the previous MAC address instead of
the new one.

How long do they typically take to notice an update
of the MAC address?

Thanks,
	Neil
