I am currently in progress in linking my ASL 3 hub which is on a cloud server on digital ocean to a brand new VOIP service that a ham user launched for the new england area that is just like the late great hamshack hotline but it’s only for select users that lives in new england and my hub uses a IP address to access anything like either putty or file explorer or even visit a feature on a browser like allscan or supermon but the owner of the VOIP service does not want to have IP addresses in the user’s dial strings in his registry that it searches when someone calls the assigned number to my hub only regular domain addresses so i’m looking to see if anyone know’s a way on how i can convert my IP address for my hub to a domain so i can provide it to the owner? my server is running the latest version of debian and latest version of ASL 3
Without doing a thing, you can just give them the address your_node_number.nodes.allstarlink.org, replacing your_node_number with your actual node number. So long as your ASL node is registered, it will point to your machine’s IP address.
I was going to suggest getting a DDNS but I like Patrick's suggestion better..
ok what’s the port number? the string is basically iax2/callsign:mypassword@domain:port/nodenumber that’s what the owner needs to be able to make contact
thought so too want to keep things on a free end where i’m just going to give it to the owner of the new VOIP service and that’s it after it’s all setup i would definitly forget all of that after few weeks unless i get a call from the owner directly with reports of downage
My DDNS is free but I have to confirm it every 30 days. His way is def easier… (of course I can call it almost whatever I want)
nice i’ll try his trick and see how that makes out also do you happen to know what port the allstar domain that he gave uses so i can give that to the owner of the new service
I assume it’s asking for the IAX port, which defaults to 4569. If you add additional nodes behind the same NAT, you have to increment them 4570, 4571, etc…
IAX defaults to 4569. So, it’ll be that unless you explicitly changed it.
That only applies if you are adding nodes on different physical machines on the same network. You can have multiple nodes on the same box, which all respond on the same IAX port.
ok i will give that info to the owner of the new service and see if that passes his checks so the NE users can call up my hub which gets them connected to my network that i built
If you want to use a domain instead of your ip address. You could just establish the dns records for the domain you wish to use. IE - Godaddy domains allow you to set your own records for free after you own the domain. If you are already using the domain you could always create a new sub domain.. such as anything.domain.com and forward that dns record to the ip address you intend to use. ( in goddady this is done under the dns records of the primary domain ((domain.com)) that you own.))
There are also way to create scripts that auto update the dns record for you via a third party company.. if your ip address is not set to static. Those services can be done for free but you’d have to create and run a script, like I did on a raspberry pi with an auto crontab command to call that script every x minutes.
This may require some apache or nginx install/settings depending on intended use.
I have sub domains established for each of the services I run so that they can be hosted in a variety of different locations/servers. Chatgpt can help you get this done BUT YOU HAVE TO watch chatgpt very closely so it doesn’t destroy your work as you move along.
You are welcome to reach out for more info.

I have a domain on ionos.com for my callsign. I the can use an A-record to convert any ipaddress to that… example: xlx.nh6fu.com which is linked to my 44 address that has my xlxserver. Pretty easy and I think I get 200+ A records for other uses For the domain, including the A records, was $20 a year..
I use DDNS free at https://www.noip.com/. I would be concerned IF you are sending a password unencrypted in your registration string and or have unencrypted ports open on your ISP firwall/router. Personally I just use a softphone and connect over WIFI or 5g via OpenVPN to my noip hostname.domainname.xxx and connect through the OpenVPN server on my OpnSense firewall and conect to my AllStar hotspot that way.
