From IPSec VPN Gateway Security Technical Implementation Guide
Part of DNS servers must be defined for client resolver.
The susceptibility of IP addresses to spoofing translates to DNS host name and IP address mapping vulnerabilities. For example, suppose a source host wishes to establish a connection with a destination host and queries a DNS server for the IP address of the destination host name. If the response to this query is the IP address of a host operated by an attacker, the source host will establish a connection with the attacker's host, rather than the intended target. The user on the source host might then provide logon, authentication, and other sensitive data.
Review the device configuration to ensure DNS servers have been defined if it has been configured as a client resolver (name lookup). If the device is configured as a client resolver and DNS servers are not defined, this is a finding.
Configure the device to include DNS servers or disable domain lookup.

globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
