Embodiment 1

[0016] Such as Figure 1A As shown, it is a flow chart of an IPv6 network-based domain name system DNS redirection method according to an embodiment of the present invention, and the method includes:

[0017] 101. Receive a DNS request message from a user terminal.

[0018] 102. If it is determined that the destination site address of the DNS request message is a site-local address, obtain a global DNS address corresponding to the site-local address.

[0019] If it is determined that the destination site address of the DNS request message is not a site-local address, the DNS request message is directly forwarded.

[0020] 103. Send the DNS request message to the global DNS address.

[0021] Optionally, after obtaining the global DNS address corresponding to the site-local address, you can change the site-local address of the DNS request message to the global DNS address, and then send the DNS request message to the global DNS address, which can also be understood as redirecti...

Embodiment 2

[0031] Corresponding to the above method embodiment, such as figure 2 As shown, it is a schematic structural diagram of a client device for DNS redirection based on an IPv6 network according to an embodiment of the present invention, and the client device includes:

[0032] The first receiving unit 201 is configured to receive a DNS request message from a user terminal;

[0033] The first determining unit 202 is configured to determine whether the destination site address of the DNS request message is a site-local address;

[0034] The first acquiring unit 203 is configured to acquire the global DNS address corresponding to the site-local address when the first determining unit 202 determines that the destination site address of the DNS request message is a site-local address;

[0035] The first sending unit 204 is configured to send the DNS request message to the global DNS address.

[0036] Optionally, the first sending unit 204 may also be used to directly forward the DN...

Abstract

The embodiment of the invention provides an Internet protocol version 6 (IPv6) network-based domain name system (DNS) redirection method and user equipment. The method comprises the following steps of: receiving a DNS request message from a user terminal; if the destination site address of the DNS request message is a site local address is determined, acquiring a global DNS address corresponding to the site local address; and sending the DNS request message to the global DNS address. The invention also provides the IPv6 network-based user terminal equipment for improving the efficiency of implementation and address management of a DNS redirection technology.

Description

technical field [0001] The invention relates to network technology, in particular to an IPv6 network-based DNS redirection method and user terminal equipment. Background technique [0002] The current IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) network evolution is still immature. In the early days, because there was no DNS address distribution mechanism similar to IPv4 (Internet Protocol Version 4, Internet Protocol Version 4) network, Microsoft drafted draft-ietf-ipv6-dns-discovery-06 (Well known site local unicast addresses for DNSresolver) defines three well-known site-local addresses (Site-Local Unicast Addresses) as DNS (Domain Name System, Domain Name System) addresses ( fec0:000:0000:ffff::1, fec0:000:0000:ffff::2, fec0:000:0000:ffff::3), if the user terminal host does not obtain DNS, it can use this by default three addresses. [0003] Although RFC (Request For Comments, Request for Comments) 3879 has clearly proposed to oppose the use of site-...
