    I am learning wcf and I have created a wcf service hosted on iis on my pc that shows up when I visit
    http://localhost/HelloWorldService/HelloWorldService.svc

    The guide I am following says I can also access it over my local network using -
    [URL]http://[/URL][your_pc_name]/HelloWorldService/HelloWorldService.svc
    This works fine

    It also say I can access it over the net using
    [URL]http://[/URL][your_pc_name].[your_company_domain].com/HelloWorldService/HelloWorldService.svc

    I retrieved my IP address from google (188.141.abc.xyz) and used that in place of [your_company_domain].com

    However it didnt work. Does anyone know how I can access this web service over the internet?
    It's not that simple. That's your public IP. That will get as far as your router, but then your router needs to know where to forward this to.

    You'll probably have to enable IP forwarding or something. Did you check your firewall settings? - also I'm sure there are WCF security options for external connections.

    OP you need to read up on something called Network Address Translation (NAT). http://en.wikipedia.org/wiki/Network_address_translation

    Your internal IP and external IP are different, with the router in between. Need to map some external ports to your local ip address.

    OK, looks like it's not so straightforward. Ill have to some reading up on this area.

    Are there specific steps I can take to make this service accessible over the net or are they different in every case?

    You could, depending on your setup, connect your server directly to the modem, you server than should have a public IP. This will allow a quick test, but you need to go down the route that WebMonkey suggests if you want a more permanent solution.

    If it's working via http on your local network, it shouldn't be a lot of work to make the service accessible outside your local network. For http, I don't believe WCF distinguishes between local network and remote requests, they're both just http requests.

    Check the NAT settings on your router, it's really just mapping a port to an IP address on the local network.
