How would i determine the country that a spcific IP address is originating from using c#. I need to use this to check if connections originate from a specific country.

A:
You can use this SQL data in your project to determine that: IP address geolocation SQL database. Download that data and import it into your database to run checks locally.
Or you can use their free API that returns XML containing the country code and country name. You'd make a request to the following URL with the IP address you wanted to check, as seen in this example:
http://ipinfodb.com/ip_query_country.php?ip=74.125.45.100
Returns:
<Response>
<Ip>74.125.45.100</Ip>
<Status>OK</Status>
<CountryCode>US</CountryCode>
<CountryName>United States</CountryName>
</Response>

Please note that the IP assignments change occasionally. So remember to update your database occasionally. (The frequency of updates you need depends on what you're doing; for simple stats you may decide that annual updates are OK).

If you don't want to use an API like perhaps hostip.info, then I'd suggest subscribing to maxmind and running a host lookup database locally.

A:
ip2cc - Lookup country and Russia region by IP address Python module with script to create database from up-to-date official data.
This Python utility loads (as frequently as you like) up-to-date information from Regional Internet Registry sites (arin, ripencc, apnic, lacnic, afrinic), as shown in the source:
url_template = 'ftp://ftp.ripe.net/pub/stats/%s/delegated-%s-latest'
sources = {}
for name in ('arin', 'ripencc', 'apnic', 'lacnic', 'afrinic'):
sources[name] = url_template % (name, name)
Once the data is loaded, queries can be answered offline and very quickly.
Can be easily modified to directly answer the original question, or used from the command line to return the country an IP address belongs to.

A:
If only you could do it online because there are free APIs and web services out there you can query for the latest data. Also you won't have to worry about outdated data as generally speaking these services do tend to keep their data up-to-date.
Since you wanted an offline option, your best option would be a paid service which allow you to download the latest data every month like IP2Location.
