Additional Skyetel IPs
-
Hey Guys,
We're going to be announcing this in a few days, and I'm dropping this here early. We're adding additional IPs to our network because we have been adding significantly more interconnectivity to the PSTN over the last year as part of an enormous network upgrade. As part of this upgrade, we simply needed more networking capacity. (This will also help us with DDOS mitigation)
Specifically, you will need to add these IPs:
44.199.94.192/27
3.144.141.64/27
3.101.177.224/27
35.85.225.96/27
3.99.65.224/27
(These IPs will do not currently support outbound calling, but we may add that ability via the dns record below at a later date)You will also need to update your outbound calling to use these:
First Priority - na.skyetel.com
Second Priority - 15.197.157.235
Third Priority - 3.33.143.204I've updated the IP Address doc here:
https://support.skyetel.com/hc/en-us/articles/360041173493 (you'll need to be signed in to read this).Anecdotally, the IPs used for outbound calling now use Anycast; so you'll be automagically connected to the region nearest you when you use those IPs.
These IPs will be required by 12/1/2021 - so the sooner you can do them the better :). We will be updating na.skyetel.com with the new IPs later this week.
Feel free to drop in a comment with feedback or questions.

Great to hear!

As soon as your DNS updates, I can start testing things. Unless I somehow get un busy, so I can make manual changes, in the next two days.

dig _sip._udp.na.skyetel.com srv
We aren't going to publish the CIDR blocks on the A record. Only the SRV.

@skyetel Well, that returned a rather lengthy list!
-
@jasgot LOL - Yes very long

@skyetel Looks like someone's loading for bear, and doing some nice front side mitigation to insure they don't get DDoS. Again, like what you guys are doing and building things properly on the front side instead of waiting till there's a problem and trying to fix it after the fact.

So it turns out that srv records above 512 bytes is not supported by Freeswitch, so we had to remove these records. I'll update you guys on a different DNS strategy shortly.
