Abstract:
1. An apparatus for relaying between a server to which a first network address is allocated and a client terminal to which a second network address is allocated, comprising: an analyzer which analyzes a message corresponding to Layer 7 of an OSI basic reference model of a received packet and determines whether a URL expressed as a literal network address is included in the message; and an address converter which mutually converts, when a URL expressed as a literal network address is included in the message, the literal network address in the URL between the first network address and the second network address; and a line interface unit having an IPv6 address, wherein the first network address is an IPv6 address or an IPv4 address, wherein the second network address is an IPv4 address or an IPv6 address and is different in form from the first network address, and wherein, when the literal IPv4 address of the URL is converted to a literal IPv6 address, the address converter converts the literal IPv4 address to an IPv6 address by applying a prefix of the IPv6 address of the line interface unit to the literal IPv4 address of the URL.
