 Reverse DNS lookup
-==============================
+==================
 
-Reverse DNS lookup involves determining the hostname associated with a given IP address.
+Reverse DNS lookup involves determining the hostname associated with a given IP
+address.
 This example shows how reverse lookup can be done using unbound module.
 
 For the reverse DNS records, the special domain in-addr.arpa is reserved. 
-For example, a host name for the IP address 74.125.43.147 can be obtained by issuing a DNS query for the PTR record for address 147.43.125.74.in-addr.arpa.
+For example, a host name for the IP address ``74.125.43.147`` can be obtained
+by issuing a DNS query for the PTR record for address
+``147.43.125.74.in-addr.arpa.``
