Microsoft has released an out of band patch to fix the "Meltdown" vulnerability on 3rd of Jan 2018. More details of the patch can be found on the official KB4056892 page.

This patch is available only for Windows 10 OS. The patch will install automatically once the PC connects to internet.

 

There has been multiple reports of some application not being compatible with this latest patch. Certain Antiviruses are causing blue-screen after installing the Meltdown patch.

There has been reports of some SSL VPN applications not connecting to the server after the patch is applied

Antivirus vendors are releasing patch to fix the compatibility issues but it may take a few days for all of them to be available.

I would recommend you to update all the important application installed on the PC before applying this patch to prevent any incompatibility issues.

If you the patch is already installed and there is some critical application causing issues, you can try to uninstall the patch and check if the application works without this patch.

 

To find the your public IP address from command line (CLI) you can use the below commands for Linux and Windows Operating systems.

Linux

curl icanhazip.com

curl canihazip.com/s

These 2 commands will generate web request and show the ip address as the response of the request.

 

dig myip.opendns.com. @resolver1.opendns.com +nocomments +noquestion +noauthority +noadditional +nostats | grep -oE "\b([0-9]{1,3}\.){3}[0-9]{1,3}\b"

This command runs DNS query and show the resolved ip address. The dns query to myip.opendns.com. using the resolver1.opendns.com DNS resolver outputs the public IP address from where the DNS query is generated.

Please note the period (.) at the end of the myip.opendns.com., this makes sure that the DNS suffix is not added to the query and query is absolute.

Windows

nslookup myip.opendns.com. resolver1.opendns.com | find "Address"

This outputs two IP addresses and the second IP address will be your public IP address
