Opened: Sep 10, 2014

Severity: 4-Minor

Symptoms

TTL lengths can get truncated due to being too large.

Impact

Bits get truncated, so the value is wrong.

Conditions

A large TTL value, above 2^31.

Workaround

Don't enter 10+ year long TTL values.

Fix Information

IP Intelligence now rejects ip-ttl values that are above 2^31. This value determines how long an IP address will be shunned.
