Bug ID 945789: Live update cannot resolve hostname if IPv6 is configured.

Last Modified: May 29, 2024

Affected Product(s):
BIG-IP ASM(all modules)

Fixed In:

Opened: Sep 16, 2020

Severity: 3-Major


Live update does not work when BIG-IP DNS is configured to use IPv6.


-- Unable to install latest updates to signatures. -- Unable to import user-defined signatures.


BIG-IP DNS uses IPv6.


If possible, use IPv4 for DNS. An alternative workaround could be to configure a working IPv4 address in the "/etc/hosts" file, by issuing the following command from the advanced shell (bash): echo " callhome.f5.net" >> /etc/hosts

Fix Information

Replaced deprecated gethostbyname which does not work well with IPv6 with getaddrinfo.
