DNS

This is an additional component for Camel to run DNS queries, using DNSJava. The component is a thin layer on top of DNSJava.
The component offers the following operations:

ip, to resolve a domain by its ip
lookup, to lookup information about the domain
dig, to run DNS queries

TODO: dependency

Headers

Header	Type	Operations	Description
dns.domain	String	ip	The domain name. Mandatory.
dns.name	String	lookup	The name to lookup. Mandatory.
dns.type	String	lookup, dig	The type of the lookup. Should match the values of `org.xbill.dns.Type`. Optional.

Examples

IP lookup

        <route id="IPCheck">
            <from uri="direct:start"/>
            <to uri="dns:ip"/>
        </route>

This looks up a domain's IP. For example, www.example.com resolves to 192.0.32.10.
The IP address to lookup must be provided in the header with key "dns.domain".

DNS lookup

        <route id="IPCheck">
            <from uri="direct:start"/>
            <to uri="dns:lookup"/>
        </route>

This returns a set of DNS records associated with a domain.
The name to lookup must be provided in the header with key "dns.name".

DNS Dig

Dig is a Unix command-line utility to run DNS queries.

        <route id="IPCheck">
            <from uri="direct:start"/>
            <to uri="dns:dig"/>
        </route>

The query must be provided in the header with key "dns.query".
