IPv6 Support
GOCDB needs to support IPv6 addresses for Sites and Services. To do this we propose adding new IPV6 fields on Site and Service objects to allow an optional IPv6 address range to be defined in addition to the existing IPv4 address.
- Requirement: https://ggus.eu/index.php?mode=ticket_info&ticket_id=100472
- Site: <SITE_IP/> and/or <SITE_IPV6/> (define an ip range for site)
- Service: <HOST_IP/> and/or <HOST_IPV6/> (define an ip range for service)
- These new fields will be optional and are not mutually exclusive (for single Site or Service, both fields could be defined).
The proposed format for <SITE_IPV6/> and <HOST_IPV6/> is:
<IPv6Address>[/<IPv6Address>]
(Where the forward slash and second address is optional, and IPv6Address has the format as described below - copied from Wikipedia):
IvP6, has a few rules that allow you to drop a lot of characters so it changes a lot. So this is the full representation – 8 groups of 4 characters separated by colon (8 groups of 4 hexiadecimals).
2001:0db8:85a3:0000:0000:8a2e:0370:7334
When there are zeros these groups can be omitted so the above can also be shown as (note the pair of double colons in the middle):
2001:0db8:85a3:::8a2e:0370:7334
Also leading zeros from each group can also be omitted so some groups may have less than 4 characters, so the second and second from last group here are valid despite only having 3 characters:
2001:db8:85a3:::8a2e:370:7334
Some IPv6 addresses have the 5-8th group all made up of zeros:
2001:adb8:85a3:7334:0000:0000:0000:0000
So all the trailing zeros can be removed so this is valid:
2001:adb8:85a3:7334
This also means that some IPv6 have an odd number of groups for instance this is valid and has 6 groups one of which is blank:
fe80::2000:aff:fea7:f7c
PI Changes
An additional element will be added for the following PI methods: get_site, get_service_endpoint, get_service_group.
The changes to the XML output are highlighed below:
