Changes to api5.yubico.com

2015-06-24

We have upgraded api5.yubico.com and as a result, its IPv6 address has changed. The IPv4 has remained the same, i.e. 109.74.193.72.

While you should never hardcode any of our IPs in your application or firewall, please do note the new address below.

New IPv6: 2a01:7e00::f03c:91ff:fe98:2109

Old IPv6: 2a01:7e00::f03c:91ff:feae:3199

If you must firewall your outgoing connections, you might be able to use DNS hostnames in your ruleset.

iptables and pf support this, but you must make sure to periodically reload your ruleset, otherwise changes to the DNS zones are not picked up.
