Name resolution

Hi John,

to give more background on my environment: my Mac is connected to a ISDN
router(using ethernet). I use network address translation to access my
provider, with internally non-routed addresses.

The interesting thing is that I can reach the update server from netscape,
but, at the same time, cannot access them from within Squeak. The same happens
when I use the Squeak browser: I can access sites using the IP number, but not
using their actual name. Interestingly it seems that if I have accessed a site
once through IP number I can then use the actual name. However,  I have to do
more tests to verify this.

I also tried adding the name with IP number into a 'Hosts' file. This didn't
seem to have any effect.
