description: As mitigations to a report from 2019 and CVE-2020-8555, Kubernetes attempts
    to prevent proxied connections from accessing link-local or localhost networks
    when making user-driven connections to Services, Pods, Nodes, or StorageClass
    service providers. As part of this mitigation Kubernetes does a DNS name resolution
    check and validates that response IPs are not in the link-local (169.254.0.0/16)
    or localhost (127.0.0.0/8) range. Kubernetes then performs a second DNS resolution
    without validation for the actual connection. If a non-standard DNS server returns
    different non-cached responses, a user may be able to bypass the proxy IP restriction
    and access private networks on the control plane.
