there is no extra vulnerability if you have dns, it just makes is look more legit comparing with an ip without dns

Thank you, your answer adds clarity to the issue. &nbsp;I know it's not hard to find available IPs, just didn't want to add one more way! &nbsp;<br />

Most of our user workstations use the same general NAT'd address of x.x.x.10 for their external IP. &nbsp;We have a group of users that would like to access a service that requires a DNS pointer with a certain domain (in this case government). &nbsp;I've always assumed it was more secure to have an anonymous IP without a DNS record pointing any port scanners right to us. &nbsp;The other alternatives are to ask the service to put in a static pointer for us or make an exception for our IP. &nbsp; <br />

Do you think there a significant vulnerability increase if I request a DNS record? &nbsp;

Anonymous IP more secure than one with DNS Record?

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.
