How does IE define what is Intranet? RRS feed

  • Question

  • We are currently using a combination of a Proxy PAC file and some excpetions within the Connection settings in IE.

    What I am interested in is the Bypass proxy server for local addresses tick box.

    What is it that IE uses to define what is classed as a local address??

  • computernames instead of hostnames ?

    so http://server and not http://server.domain.something

    maybe this will help:

    some more about intranet/internet zones:

  • Thanks for the reply.

    I had seen those KB articles but this does not seem to tie in with what I experience!

    For instance in the Security | Intranet Zone we have our domain name added via Group Policy.  To me this would imply that anything with our domain name extention should be classed as Intranet and therefore not use the Proxy if the tick box is selected in connections to Bypass the proxy for local addresses.

    But in reality this does not work. However if I then add the domain name to the exceptions list in the connections settings this then does work!

    So it would seem to me that the two parts of IE do not seem to 'talk' to each other!

    Just seems to be a little hit and miss!

  • like KB262981 says: By default, only host names are checked when the Bypass proxy server for local addresses option is turned on.

    it's always a good idea to include/define your local *.domain.local in the proxy exceptions and always split internal and external machines by their dns suffix (don't use bla.local for "external" machines).

    I think the intranet zone config doesn't do anything with the proxy settings and is only used for a seperate zone config (intranet/extranet machines could behind proxies as well)
