Abstract
The present invention can prevent a fuzzy image, which is caused due to insufficient bandwidth when the bandwidth necessary for transmitting a content cannot be secured, to be displayed on a display device. When a relay apparatus () receives, from a DNS server, a DNS response packet regarding a domain name of a server which transmits a content, a condition judging section () in the relay apparatus () judges whether a required bandwidth for the content corresponding to the domain name can be secured in a communication path connecting to another relay apparatus (). If the condition judging section () judges that the required bandwidth cannot be secured, a DNS modifying section () in the relay apparatus () rewrites a reply IP address included in the DNS response packet to an IP address of the relay apparatus ().
