Configuration for the Resolver

Fields

ndots: usize

Sets the number of dots that must appear (unless it's a final dot representing the root) that must appear before a query is assumted to include the TLD. The default is one, which means that www would never be assumed to be a TLD, and would always be appended to either the search

timeout: Duration

Specify the timeout for a request. Defaults to 5 seconds

attempts: usize

Number of attempts before giving up. Defaults to 2

validate: bool

Use DNSSec to validate the request

ip_strategy: LookupIpStrategy

The ip_strategy for the Resolver to use when lookup Ipv4 or Ipv6 addresses

cache_size: usize

Cache size is in number of records (some records can be large)

use_hosts_file: bool

Check /ect/hosts file before dns requery (only works for unix like OS)
