The firewall/router I use does periodic Internet connectivity tests by pinging a few static IP addresses, however since they're things like 8.8.8.8 they're vulnerable to false positives which leads to annoying alerts.  Does anyone know of any easily-reachable NZ static IP addresses I could use in place of the built-in US ones?

Probably best to find one that your ISP hosts - have you tried pinging their DNS servers?

Who's your ISP? Best to use one of the servers else just use 1.1.1.1 which will hit Cloudflare's nodes in AKL or CHC.

Yeap ping is a whole lot better than Google DNS too.

Ah, so 1.1.1.1 is local... I've currently got it set to the ISP's DNS servers and that, let's see if the FP's go away.

1.1.1.1 is not guaranteed to be local. It could be anywhere in the world depending on network conditions.

OK, so that doesn't seem to have fixed it.  Opened a ticket with the vendor.

What firewall/router are you running and who's your ISP?

Firewalla, I think their link liveness-detection mechanism may be a bit too simplistic.

Documentation shows they do quality tests by pings on a freq. Most do this now and use standard points like Cloudflare (1.1.1.1) or Google (8.8.8.8). If you seeing decent pings doing them manually ~ 30msec to Google or ~ 15msec to Cloudflare depending on your ISP - then it could be a firmware issue as opposed to a wider network issue.

Would typically turn those tests off anyways and use something like SmokePing for better results.

Interesting!  I did not know this.

 

For me from a Vodafone connection, 8.8.8.8 is 9 hops and 37ms away.  1.1.1.1 is 8 hops and 9ms away.  (Unscientific testing using Wi-Fi and getting the average of 20 pings.)

 

For my brief testing in the past, I've occasionally picked on nz.pool.ntp.org which I believe delivers up one of a selection of NZ-based NTP servers.  pool.ntp.org: NTP Servers in New Zealand, nz.pool.ntp.org (ntppool.org)

Does depend on your ISP and routes to certain points. I typically use speedtest servers around the country and see -

~ 2msec to servers in Wellington
~ 10msec to servers in Auckland
~ 5msec to servers in Christchurch
~ 30msec to servers in Sydney

via one of my Spark connections in Wellington.

An update on this, does anyone know of any pingable addresses on 2Degrees?  You can't ping their DNS servers, and I'd like to have something that isn't half-a-dozen hops away, I just need to check whether I can get from the device to 2Degrees' network.

 

Edited to add: The reason they're not pingable is that the published values are wrong, DHCP returns addresses 118.148.12.10 and 118.149.12.10 which are pingable.
