145953 - Wrong DNS lookup after DNS server address has been changed

Status: RESOLVED DUPLICATE of bug 64857

(Core :: Networking, defect)

Description

[Takahide HIGUCHI]

Since I'm using mozilla on linux laptops, /etc/resolv.conf is often changed by
getting DHCP leases from different networks. Since Mozilla seems to cache IP
address of DNS server only at boot time, Mozilla can't resolve URLs after such
an update of /etc/resolv.conf if the cached DNS server address is not reachable.
 
For example, If I boot mozilla at my office, DNS server address, which is
192.168.1.1, is cached. When I go home, or go to conference room with wireless
LAN card, my laptop gets new DHCP lease but Mozilla does not update cached DNS
server address. If 192.168.1.1 is not reachable from there, Mozilla no longer
resolve URLs and I have to restart it.
