ignore CNAMEs in RDNS-mode #1460
Suppose your provider uses RFC 2317 (or RFC 4183 for that matter). The output of nslookup could look like the following:
2.120.22.172.in-addr.arpa canonical name = 2.0/26.120.22.172.in-addr.arpa.
2.0/26.120.22.172.in-addr.arpa name = rajesh.intern.prauscher.de.
Without this filter, check_dns would check the string against "2.0/26.120.22.172.in-addr.arpa., rajesh.intern.prauscher.de." which will fail for obvious reasons.
In forward DNS, this is achieved in line 165, as nslookup will print the address separate from the CNAME-resolving.
