Summary
Netfoil, a DNS-related software package, does not decrement the time-to-live (TTL) value on cached records, so outdated DNS records may continue to be served to clients after they should have expired.
Read the original description
TTL was not decremented, so stale records would continue to be served.
What to do
Upgrade to a fixed version: 0.6.1.
