I've only recently installed MSSQL and I want to connect to my DB with Python.
However when I look up my IP with canyouseeme.org it tells me, my IP is 193.x.x.x
However if I open TCP/IP protocol for SQLExpress through SQL Configuration manager my IP4 IP is shown as 192.x.x.x.
With IPconfig in CMD my IP shows up again as 192.x.x.x.
Can somebody please explain this to me? Or point me to a clear "MSSQL server for dummies" tutorial which covers this? Given I'm not able to find it myself.
When you check your IP from canyouseeme.org it's showing you a public IP address that let you connect to the internet. But when you use IPconfig in cmd or in your SQL configuration manager you are getting your local IP for your device, this IP is given to you by your router whereas your public IP is assigned to you by your ISP.
So you should use your local IP in your case 192.xxx, you won't be able to access it out side your local network also.

I want to connect to my server from another network, my server hasn't got an outside ip adress. I want to reach the sql server from where I host my website. I host my website somewhere else (not in my network).
Your SQL Server will have to be visible to the server from which you host your website.
I'm assuming you want to access the data in SQL Server to generate some content for your website.
There are 2 simple ways to do this:
Static IP - Ask your ISP for a static IP address for your local
network, you can use this in the connection string. This is preferable & more stable, since it will always be in sync.
Dynamic DNS - If your ISP won't give you a static address or you don't want to pay for it. You sign up with a DDNS service provider, they give you a domain name, like ferrysqlserver.ddns.org, and your network is visible to the internet via that name. Some routers support DDNS, otherwise you may have to run a service application that keeps your external ip address in sync with your DDNS provider.
Once you have either of those working, your network is now available to the internet, but nothing is likely accessible.
What you have done so far is to create a path from an internet name to your local router.
To make SQL Server accessible, you need to find out which ports your SQL Server uses (default is 1433). It's possible you may need to open other ports as well if you connect to SQL in a different way.
On your router, find the port forwarding options, and enable port forwarding to the local network ip address of your SQL Server, for port 1433.
This step maps connections from the internet to port 1433 of your router, and forwards those connections to port 1433 of your SQL Server.
Good luck.
I created a virtual machine and install our own copy of MS SQL2016. I can connect fine from the VM but when I try to connect from outside (my office) it say that it cannot find the network instance. I have tried the Server name (Mapped in host file) the DNS name connected to the public IP and even the public IP. I have enabled the TCP/IP protocol and set the port (1433), set up a Windows firewall rule, set up incoming rule in Network security group, read articles and tried many things but still same message .
Anyone have an idea?
I have created database and user and give all the privilege to the user.When i give the IP as Database host.It will show the following errors.Giving hostname as localhost it will work fine.
I am using phpmyadmin 3.3.2...
The error message is given below.
Failed to connect to your MySQL database server. MySQL reports the following message: Can't connect to MySQL server on '192.168.85.10' (111)
It seems that the IP address you use is your "external" IP and not the IP localhost would resolve to, which is most of the time your loopback: 127.0.0.1.
So if you are trying to connect from the same computer as the database is running you should use 127.0.0.1 as the IP address.
If you are trying to connect to your database from another computer on the network, you should enable MySQL remote access in your my.conf (MySQL config file). Because by default MySQL disables remote incoming connections.
You do this by setting the "bind-address" line to your real (external) server IP as such:
bind-address = 192.168.xx.xx (assuming its on your local network)
Or put the bind-address in comment.
Also make sure that the skip-networking option is commented as such:
#skip-networking
And then restart your MySQL server.
Now also make sure that your MySQL users are also allowed to connect from locations other then "#localhost".
I hope this helps!

I need to access an SQL Server that is on a machine behind a firewall and you access this machine using an ip address like 95.95.95.33:6930 (not the real ip address) ... But, you get my point that by accessing 95.95.95.33 on port 6930, the firewall routes the requests to that particular machine ...
My question is ... How do you construct a connection string to access the machine at address 95.95.95.33:6930 and then further access the SQL Server on port 1433 or maybe a different port like 8484 ???
Thanks
Mike
well, you build the connection string like this
"Server=95.95.95.33,6930;database=mydb;..."
the firewall/nat will have to route that to the correct machine/port of the SQL server for you.
All you should worry about is the public address and port number of the SQL server. It makes no difference to you to which internal machine and port number the connection is forwarded to.
You then build a connection string as described on connectionstrings.com:
Data Source=95.95.95.33,6930;Network Library=DBMSSOCN;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword;
DBMSSOCN=TCP/IP. This is how to use
TCP/IP instead of Named Pipes. At the
end of the Data Source is the port to
use. 1433 is the default port for SQL
Server.
I don't know of the default server name. Can you please help me because I need to work on our project to connect vb.net with wamp server, and for that to happen, I must know the server name that I will put on the codes. Please, thanks in advance.
The WAMP server doesn't maintain a name. You connect to it via an IP address... do you not know the IP of the machine it's installed on?
If it's on your own computer, you can connect to the Sql server from code by connecting to 127.0.0.1:3306 (default port).
If it's not on your machine, find the ip address of the machine it's running on by going to the command prompt and typing 'ipconfig'.
Then use that IP address and port 3306 (or whatever port you defined, 3306 is just default)
Default access will be via localhost or 127.0.0.1. Might not work (rarely) if it was modified before.
The following should work provided (provided mySQL port is default at 3306) :
Dim connectionString As String = "Driver={MySQL};SERVER=localhost;DATABASE=student;

Just check connectionstrings.com, one of the best resources out there.
