The Deploy.ps1 script gets a IPV6 Public IP instead of and IPV4, causing an error while setting up the SQL firewall rule

[Giancarl021]

Describe the bug
When running the Deploy.ps1 file, I get an FirewallRuleNotIPv4Address, showing that the service ifconfig.me is returning the wrong IP type.

To Reproduce
Steps to reproduce the behavior:

1. Execute the Deploy.ps1 PowerShell file;
2. On the line 350, it will grab the IPV6 IP address, instead of the expected IPV4;
3. An FirewallRuleNotIPv4Address error will be thrown

Expected behavior
The correct IP type to be returned by the ifconfig.me service, which will lead to a clean execution.

Additional context

• Maybe this problem arises only on specific machines or User-Agents, I'm not sure;
• A potential solution would be to simply change the Public IP service, such as ipify (which got my correct IPV4 address).
