Validating an IPV6 address from an IPV4 network
Systems and methods are described herein for validating an Internet Protocol (IP) version 6 (IPv6) address from an IP version 4 (IPv4) network. A method, according to one implementation, includes a step of receiving an IPv4-based request from a validation server that is configured to support an IPv4 address space. The method further includes a step of sending an IPv6-based request to a domain supporting an IPv6 address space. Also, the method includes receiving a response status code and domain validation information from the domain. Then, the method includes a step of passing the response status code and domain validation information to the validation server.
1 . A proxy server comprising:
a network interface;
a processing device; and
memory configured to store computer logic having instructions that, when executed, cause the processing device to perform steps of:
a) receiving an Internet Protocol version 4 (IPv4)-based request via the network interface, wherein the network interface is configured to receive the IPv4-based request from a validation server that is configured to support an IPv4 address space,
b) sending an IP version 6 (IPv6)-based request via the network interface to a domain supporting an IPv6 address space,
c) receiving, via the network interface, a response status code and domain validation information from the domain, and
d) passing the response status code and the domain validation information, via the network interface, to the validation server.
2 . The proxy server of claim 1 , wherein the IPv4-based request is configured to represent a first HTTP GET request.
3 . The proxy server of claim 2 , wherein, before the step of sending the IPv6-based request to the domain, the instructions further cause the processing device to perform a step of converting the IPv4-based request into the IPv6-based request, the IPv6-based request representing a second HTTP GET request for requesting the domain validation information from the IPv6 address space.
4 . The proxy server of claim 1 , wherein the validation server is configured to execute a domain validation procedure configured to confirm that an administrator associated with the domain is authorized to manage the domain.
5 . The proxy server of claim 1 , wherein the validation server is associated with a cloud-based Certificate Authority (CA), and wherein the step of passing the domain validation information to the validation server includes a step of enabling the validation server to automatically validate IPv6 addresses.
6 . The proxy server of claim 5 , wherein the CA is configured to operate within the IPv4 address space.
7 . The proxy server of claim 5 , wherein the CA is configured to issue digital certificates after automatically validating the IPv6 addresses.
8 . The proxy server of claim 1 , wherein the proxy server is arranged externally with respect to the validation server.
9 . The proxy server of claim 1 , wherein a response status code of 200 indicates a successful request.
10 . A method comprising steps of:
receiving an IPv4-based request from a validation server that is configured to support an IPv4 address space;
sending an IPv6-based request to a domain supporting an IPv6 address space;
receiving a response status code and domain validation information from the domain; and
passing the response status code and the domain validation information to the validation server.
11 . The method of claim 10 , wherein the IPv4-based request is configured to represent a first HTTP GET request.
12 . The method of claim 11 , wherein, before the step of sending the IPv6-based request to the domain, the method further comprises a step of converting the IPv4-based request into the IPv6-based request, wherein the IPv6-based request represents a second HTTP GET request for requesting the domain validation information from the IPv6 address space.
13 . The method of claim 10 , wherein the validation server is configured to execute a domain validation procedure configured to confirm that an administrator associated with the domain is authorized to manage the domain.
14 . The method of claim 10 , wherein the validation server is associated with a cloud-based Certificate Authority (CA), and wherein the step of passing the domain validation information to the validation server includes a step of enabling the validation server to automatically validate IPv6 addresses.
15 . The method of claim 14 , wherein the CA is configured to operate within the IPv4 address space.
16 . The method of claim 14 , wherein the CA is configured to issue digital certificates after automatically validating the IPv6 addresses.
17 . A non-transitory computer-readable medium configured to store a conversion program having instructions that, when executed, enable a processing device to:
receive an IPv4-based request from a validation server that is configured to support an IPv4 address space;
send an IPv6-based request to a domain supporting an IPv6 address space;
receive a response status code and domain validation information from the domain; and
pass the response status code and the domain validation information to the validation server.
18 . The non-transitory computer-readable medium of claim 17 , wherein the IPv4-based request is configured to represent a first HTTP GET request, wherein, before sending the IPv6-based request to the domain, the instructions further enable the processing device to convert the IPv4-based request into the IPv6-based request, and wherein the IPv6-based request represents a second HTTP GET request for requesting the domain validation information from the IPv6 address space.
19 . The non-transitory computer-readable medium of claim 17 , wherein the conversion program is configured in a proxy server arranged externally with respect to the validation server.
20 . The non-transitory computer-readable medium of claim 17 , wherein a response status code of 200 indicates a successful request.
