Opened: Nov 06, 2017
Severity: 4-Minor

Symptoms

The current IPv4 address for b.root-servers.net is 192.228.79.201. The IPv4 address for b.root-servers.net will be renumbered to 199.9.14.201, effective 2017-10-24. The older number will be invalid after that date.

Impact

The impact is likely minimal, at most a single timeout for pending TLD queries when they happen to round-robin onto an old IP address, probably not more often than the hint's TTL, which is more than a month, and even this should cause a timeout only when the old IP actually stops responding.

Conditions

Several profiles contain the b.root-servers.net IPv4 address as 192.228.79.201.

Workaround

Update the root hints for all affected profiles manually except the hardwired ones.

Fix Information

The IPv4 address for b.root-servers.net has been renumbered to 199.9.14.201, effective 2017-10-24.

Behavior Change

The IPv4 address for b.root-servers.net has been renumbered to 199.9.14.201, effective 2017-10-24, according to InterNIC. The old IPv4 address (192.228.79.201) will continue to answer queries for at least 6 months.
