Globus and IPv6?

[Tim Chown]

Hi,

What’s the latest news regarding Globus and IPv6 support?

I recall experimental support was tested in the 2021 Data Mover Challenge, but has any code made it towards release, or is there any concrete plan to do so?

Many thanks,
Tim

Hi Tim,

 

I don’t know if it’s officially support, with GCSv5, when you set up a DTN, it’s possible to specify the -I (or --ip-address) option multiple times, once with an IPv4 IP and once with an IPv6 IP.  Globus HQ then uses both IPs to propagate your GCSv5 `xxxx.yyyy.data.globus.org` domain, so when you do a DNS lookup you’ll see both IPv6 and IPv6 addresses.

 

That means, at the very least, users accessing your collections directly (through a web browser) can use IPv6, and I think GCS-to-GCS transfers would also work.  Of course, that assumes the other end is also using IPv6.

 

I don’t think that Globus HQ (the Globus web site, relay.globusonline.org, etc.) support IPv6 yet.  And I have no idea about GCP.

Hi Karl,

That’s very encouraging, thank you. We’ll look to do some tests.

Any official comment also very welcome.

Best wishes,
Tim

Hi,

This is on our list of prioritized work for when the tooling support for migration to GCS version 5 is complete. The work will include updates to the hosted services, and Globus Connect Server/Personal to support IPv6, and expect support sometime mid-next year.

Thanks,
Rachana
