More information and/or link(s) to ticket(s)
gfal2 is plugin based, so it all depends on the plugin
- HTTP: neon supports IPv6
- SRM: gsoap supports IPv6.
- GridFTP: it is enabled - https://its.cern.ch/jira/browse/LCGUTIL-4
- DCAP: unknown
- LFC and RFIO: should work
- BDII: OpenLDAP does support ipv6
Note on gsoap - this is used for WS in a number of cases. It supports IPV6 but this has to be enabled at compile time, so in certain builds it could be missing.
lcg_utils works provided the appropriate Globus libraries are installed and environment variables set.

With bdii-5.2.23-1.el7.noarch I needed to add BDII_IPV6_SUPPORT=yes to /etc/bdii/bdii.conf (or /etc/sysconfig/bdii) for it to also listen to IPv6.
Before setting:
# ss -tlnu|grep 2170
tcp LISTEN 0 128 *:2170 *:*
After setting:
# ss -tlnu|grep 2170
tcp LISTEN 0 128 *:2170 *:*
tcp LISTEN 0 128 :::2170 :::*
