I trying connect to azure sql server (xxxx.database.windows.net) through datacenter ip addres, i changed connect policy by proxy, but now i don't know how connect to instance the sql server.

You may have to add the datacenter IP range as a rule on the Azure SQL Database firewall rule. Please download and read this document to know the current IP range of the datacenter where your database resides.
Alternatively you can also set "Allow Access to Azure Services" to On (see image below), although this option configures the firewall to allow all connections from Azure including connections from the subscriptions of other customers.
In addition to configure the firewall, for security reasons make sure your login and user permissions limit access to only authorized users.
This guide may provide you additional valuable information to connect to your Azure SQL databases.

I have an application running in Azure Batch which tries to connect to our customer's SQL Server also running in Azure. The connection fails, because the customer has default firewall on the SQL Server and the IP address of the Azure Batch node is not allowed in the firewall rules.
When I try to connect from the Azure Batch application to out SQL Server running in another subscription, the connection is successful.
Why in the first case the connection does not work and in the second case it works?
Is it possible to connect to the customer's SQL Server? I cannot give them an IP address to allow in the firewall, because the IP address of the Azure Batch is dynamic.
The solution is to set this switch to Yes in SQL Server → Security → Firewalls and virtual networks. With this setting, it is possible to connect from Azure Batch application to SQL in another subscription.
thanks in advance
I have the following scenario:
SQL database on a SQL Server on premise (source)
SQL database on aAzure (target)
I access to my network from a VPN (F5 - Big IP Edge Client)
I created and configured an Azure VPN Gateway to connect to the VPN. With this configuration and the use of Azure Data Factory, it is possible to see my on-premise database and read the data.
I want to restrict access to the Azure SQL database only to clients from my on-premise network (or connected to the VPN). When i try to set the firewall ip rules, Azure only allow to register public ips address but not recognice IPs from my onpremise network.
Questions
1)It is possible to set access to only clients from insede my private network. How to get this?
2)Is there another better option to get this secure connection?
Regards
SQL Azure maintains a firewall for the SQL Azure servers, preventing anyone from connecting to your server if you do not give their IP address permissions. Permissions are granted by client IP address. Any user’s desktop application that connected to SQL Azure would need to have the SQL Azure firewall open for them in order to connect. The client IP would be the IP address of the desktop machine as seen by the Internet.
Any desktop computer can access SQL Azure as long as it has Internet access, and port 1433 open for outbound connections.
If you're trying to connect from within a corporate network, you can add user machine public IP or the VPN endpoint IP if all user connect through it. Further to allow access from specific on-premises machines, firewall rules can be used to limit connectivity only to your public (NAT) IPs.
A more secure option, you can set up server-level firewall rules (Server-level IP firewall rules apply to all databases within the same server) and Setup database firewall rules (Database-level firewall rules only apply to individual databases, can be configured using Transact-SQL statements, and only after you've configured a server-level firewall rule.)
Create server-level and database-level firewall rules
Configure an Azure Active Directory (AD) administrator
Manage user access with SQL authentication, Azure AD authentication,
and secure connection strings
Enable security features, such as Azure Defender for SQL, auditing,
data masking, and encryption

I would like to connect to Azure SQL server from a Window server via SSMS. In the “set server firewall” from Azure, I have given my server IP ( from the system I would like to connect). I need to know the destination IP adders of the Azure DB Server. From Azure portal the location is showing central US . To allow firewall I need to know the destination IP address.
My questions are:
1. As Central US could have multiple IP addresses, do I need to provide all IPs to my Firewall team?
2. How can I know the destination IP address ( i.e. Azure) so that I can provide that to my firewall team?
Note: From SQL server management studio, the tcp default port for SQL is enabled and services are running fine.
Hope I have explained it correctly.Thanks
No. You cannot get a static IP address assignment for your Azure SQL Database. Moreover, what you refer (mysqlserverdatabase.mysql.database.azure.com designates your Azure SQL Database Server, not a single Database. This is a logical server, in which you can put up to 149 Databases (150 with the Master DB).
You have to workaround your requirement for static IP address assingment to work with the DNS Name (mysqlserverdatabase.mysql.database.azure.com).
Otherwise if your company firewall can't work with the DNS Name ,you need to set the server connection policy to Proxy as documented in Azure SQL Connectivity Architecture. This allows the database gateway to proxy all traffic between the client and the DB server. The gateways all have static IP addresses, which are listed in the above document.
If you have setup a VNet in Azure, checkout VNet Service Endpoints to connect Azure SQL.

We have a sql server firewall setup with no IP access and "Allow Azure Services" flag also set to off.
I understand this means no azure services and no external clients will be able to access the sql server and database.
however, when i try Import Database option on sql server, with bacpac stored in azure storage, we get a strange error of an IP that needs to be given access in sql server firewall. The error reads.
Client with IP address 65.52.129.125 is not allowed to access the server.
While our azure infra is in West Europe, there is no mention of what this IP belongs to and what is the purpose of it.
The same error of course also occurs from Infra as a code approach and CI-CD Pipelines. and I think adding an IP without any information is risky.
Has anyone faced this before? or if anyone knows , what is azure database import using underneath for which this IP needs access and will it always be the same?
65.52.129.0 - 65.52.129.255 is an IP address range owned by Microsoft Corporation and located in Netherlands.
Please read the following explanation about why you should enable Azure Services access on the firewall at least while doing export/import operations. When you finish import/export operations, then disable Azure Services access.
"The IP address space used for outbound connections from the Import/Export Service infrastructure to the target logical server is not documented, and is subject to change at any time. Therefore, given that connections to the target Azure SQL Database server are gated by server firewall, the only fully reliable way to ensure that the Import/Export service will be able to connect is to enable the firewall rule that allows access from all Azure services (or, equivalently, from the 0.0.0.0 IP address). Obviously, opening the firewall to a large IP address space is a network security risk. Security conscious organizations will want to mitigate this risk by disabling this firewall rule as soon as the import operation completes successfully..."

If I create a VNet named mySiteToSitevNet and configure it for Site-To-Site connectivity. I create a Virtual Machine assign it to use mySiteToSiteVNet as its network. I Install SQL Server on it.
Do i get Public IP to connect to that SQL Server from my WebApp which does not have VNet associated to it?
If not, how do I make my WebApp connect to that SQL Server and use the database?
There are 2 options:
Since you already have a Sign to Site VPN then you can VPN in from your website's box to enable it to access the SQL and that's the most secure way.
If for some reason you don’t want to VPN in, first you need to figure out why you don’t want to do this. If there’s a really good reason to not VPN in, then continue with setting up direct Internet access to the SQL Server.
To open an endpoint browse to the VM in the Azure portal. Open the properties of the VM in the Azure Portal, then click the “All Settings” option. Then select “Endpoints”. It’ll look something like this.
If you see a “SQL Server” endpoint with 0 ACL Rules then the work is half done (shown above). If there are ACL rules then you should be finished unless you need to add more ACL Rules.
If there is no SQL Server endpoint click the “Add” button at the top of the Endpoints blade. Name the endpoint “SQL Server”, select the protocol TCP, then set the ports to 1433 (or whatever TCP ports you want to use, but 1433 is the default). Select to setup access rules for whoever needs access and block any subnets that don’t need access and then OK back to the VM’s properties.
At this point you can connect to the SQL Server instance through whichever method you’ve setup. If you are using either VPN option you can just connect to the Virtual Machine’s network name. If you are going through the public endpoint (again this is REALLY NOT recommended) you’ll need to connect to the machines full DNS name.
Any VM deployed in a Virtual network can also be exposed through public Internet, so the answer to your question is Yes, it can be given a instance lvel public IP address (https://azure.microsoft.com/en-us/documentation/articles/virtual-networks-instance-level-public-ip/) or port behind the public load balancer (https://azure.microsoft.com/en-us/documentation/services/load-balancer/)
