I am using a script bought from Code Canyon (a weather script) and the script uses MaxMind GeoIP Javascript Web Service to determine my users current location. The question I have is how does MaxMind (or other geolocation services) determine the location?
When it determines my location it is on average about 30 miles away from my actual city. Why and how does it determine the location being there and not closer? I assume this has to do with my ISP and my ISP routing. Is this correct?
The location it is showing you is the location of your internet server.
If you are using the geolocation code which uses your ip address to get the current location then it will show the location of your host server.
Your ISP assigns you an IP when connecting. Obviously, the ISP bought that IP at one point, and the geolocation service you are using has an entry for it, in this case, a data center of your ISP.

We are using IP geolocation vendor in our application. And vendor will update their database in monthly basis.
But IP address is getting assigned to different country over time. Any proper reference or standard for this changes?
You can publish a geofeed file and host it in your website. The format is based on RFC 8805.
However, it is still up to the geolocation vendor to trust your feed and take into records. IP geolocation is under heavily manipulation due to many reasons.
More than a question this may be general information . I am using a VPN service and located in the Middle East. I've found most (if not all but one) IP geolocation webpages shows my location as New York which matches the VPN IP address. But the service whatismyipaddres_dot_com shows the correct IP address and my location in Kuwait. Clicking some links on the mentioned webpage it takes me to a page showing they use several services from which one is showing Kuwait and the other two New York. However,contary on the expected "majority vote", they pick the single one different which, in fact, is right. As you can see they do not mention the name, but I believe the provider is Maxmind (maxmind_dot_com).
Sorry, not allowed to post images!!
Does anyone knows what they may be using ( router MAC? Google account ?).I use VPN to access ESPN , etc , but if this method is used by all other geoloc services in the future ,it will render the VPN unusable !
The web site whatismyipaddress dot com is using a mixture of HTML5 geolocation and IP geolocation.
Most likely your MAC address are being used to geolocate the location using HTML5 than using IP address geolocation.

I would like to set automatically timezone on my Arduino with ethernet card. So I'd like to know if there is the service which can return client timezone on http request.
Since you have nothing but the IP address, then the only possibility is to guess at the location via IP geolocation. For example, you could use ipinfo.io, or freegeoip.net, or any number of other sources. (A Google search for "IP Geolocation" will show many results).
Of course, IP Geolocation isn't all that accurate, and you may have many incorrect results. If your device has GPS or some other source of location data, that would be much more accurate than IP Geolocation.
Once you have a latitude and longitude, you can call one of the API's listed here to return the time zone.
I am looking into getting a geolocation database. I am trying to understand the difference between a paid and a free service besides how accurate the results are.
I want to display data on the page based on the user's location. Should I user server side or client side to check the location and display the data accordingly? I can imagine how to do it server side, but not client side.
If I want to get the user's ip, country, region, city, and show the cities within x km around that city, I would also need the Latitude and Longitude correct?
I was looking at
http://freegeoip.net/
and

option: DB5
I suggest maxmind database for Geo location, I have used maxmind database for my
website
the link of maxmind data base is-http://maxmind.com/geoip/legacy/geolite/
freegeoip uses maxmind GeoLite2 database. You could as well download it yourself (~25mb) and lookup on your server which would be faster.
how do one determine location based on ip? I'm not asking for any product or service, but rather how to go about implementing it technically.
The ip to country is a rather static mapping. What about more specific locations?
geobyte is a good service to locate ip address. If you are thinking about an algorithm to find location based on IP, I think there is none. It is basically a database look up and you will retrieve the location based on the IP address.
