Can I identify my Internet Provider from my Internet connection

Dell Inspiron 1501, Windows XP Home Edition

I use Outlook Express for my three email addresses.
I am currently in a new location   which has a WiFi connection which works well.
However I cannot send emails from two of the addresses - I assume the Outgoing Server Code is wrong.

  Can I discover who my provider is  from this connection (so that I can look for the correct outgoing server code)

How to confirm your IP address
Open Internet Explorer and browse to an IP identification web site; here are some examples: 
Take a note of the IP address that is reported, it will be in the format

Once you have identified your IP address, you need to confirm which ISP it belongs to.

How to confirm which ISP your IP address is allocated to
Open Internet Explorer and browse to: 

Enter the IP address you have obtained and press "Search".

The Results page will contain a substantial amount of information, it will probably contain some identification data for your organisation such as your address, telephone number etc.  Scroll to the bottom of the page and you should find a block of information starting "route:" which will contain an entry "descr:" which will identify your ISP. Here is an example entry:

descr:           Research Machines Plc
descr:           Internet for Learning
origin:           AS5503
mnt-by:          AS5503-MNT
source:          RIPE # Filtered

I came up with this. Does this mean that Comunitel-MNT is the provider? Can I get the outgoing server information for that company?

descr:          Comunitel Global PA Block
origin:         AS12357
mnt-by:         COMUNITEL-MNT

This is what I am getting. I tried many variations of and and but to no avail.  The hotel where I am staying seem to know little about outgoing servers. They do agree that Vodafone is the IP - Geo Information

Does not solve my problem, but gave me good advice on what needed to be done.
Thank you Eamon.  I wasn't expecting inclusion for a 4 word suggestion that didn't work, so it's appreciated.
