Last updated March 2020
Name
dns_fallback_to_tcp — whether or not to fail over to TCP in place of UDP
Synopsis
dns_fallback_to_tcp = false
Description
Momentum uses User Datagram Protocol (UDP) for DNS queries. However, the size of a UDP packet is limited and a DNS query can exceed it. Set this option to true and Momentum tries first with UDP then fails over to TCP if the query response is too large. This avoids having lengthy DNS responses truncated.
The default value for this option is false.
Scope
dns_fallback_to_tcp is valid in the global scope.
