DNS

negative performance impact of ndots:N

This is a short form of the original

If traffic is external and there are several lookup domains ndots:N will cause high amounts of DNS traffic before domains are resolved correctly.

ndots:5 will result in 4 local lookups for this example config:

# /etc/resolv.conf
nameserver 100.64.0.10
search namespace.svc.cluster.local svc.cluster.local cluster.local
