A web server, email server and any server device directly accessible from the Internet are candidate for a public Internet Protocol address. A public Internet Protocol address is globally unique, and only assigned to a unique device. The are two types of Internet Protocol (IP) addresses: Public and Private. I have various public ip addresses for various application servers outside of my internal network & my goal is to allow these addresses on my firewall but i have to know the subnet masks i think. Well depending upon the end-point connecting this may well vary and you'll need to have a conversation with he IT folks at the remote point.
Every device connected to the internet has a Private IP Address and Public IP Address provided by the Internet Service Provider. You will find below the steps to find your Public and Private IP Address.
Public Vs Private IP Address
In a typical Network setup, the Modem/Router connects to the internet using an External IP Address and other devices connect to Modem/Router using their own Private IP Addresses.
The External IP Address of the Modem is assigned by the ISP (Internet Service Provider) and this is visible to other devices on the internet.
The Internal or Private IP Address is assigned by the Modem to your Computer, Phone and other devices and this can only be seen by other devices using the same WiFi Network.
In short, the External IP Address (assigned by Service Provider) can be seen by other devices on the internet, while the Internal IP Address is not visible to other devices on the internet.

Your Public IP Address is assigned by the ISP (Internet Service Provider) and this can be easily viewed by typing What is my IP Address in Chrome, Safari and other web browser.

DNSBL or Domain Name System-based Blackhole List
DNSBL is a software mechanism created in the attempt of stopping email spam. There are dozens of such systems, which use different criteria to list or delist IP addresses. The operation of DNSBL systems is controversial as they can be used by various organisations to impose online censorship.

Why is my IP address blacklisted?
Your IP address may be blacklisted for several reasons, but mainly it is related to spam. If you send unsolicited emails or you share the IP address with someone that sends spam, then it's likely that the IP address is blacklisted at some point. Also, the IP addresses are blacklisted if they are used for other malicious activities on different sites.
Another reason for seeing your public IP address blacklisted is if you are using a proxy. Don't you know if you are using a proxy or not? Take the proxy check test.
