# go-nsupdate
|
||
|
|
Update dynamic DNS records from netlink.
|
||
|
|
|
||
|
|
`go-nsupdate` reads interface addresses from netlink, updating on `ip link up/down` and `ip addr add/del` events.
|
||
|
|
|
||
|
|
The set of active interface IPv4/IPv6 addresses is used to send DNS `UPDATE` requests to the primary NS for a DNS zone.
