Updating Multiple noip.com DDNS Hosts?

[bozolino]

i have configured the three host names in my noip.com free account to point to my router, my nas and my imac so that all machines are consistently available from the same urls both from my LAN and from WAN when i'm abroad. however, my router can only update one noip.com address at a time. is there a script to update all three addresses at once from the router? i've searched the interwebs and tried some bits of code, but none of it made sense...

If they have the same IP why having 3 hostname resolving to the same IP ? I guess it's the port or the link that change between those 3 hosts ?

curl is available, hence you can always write shell script to update your custom host.

I use dnsomatic.com for my 2 noip.
It works also for other DDNS, and it's free.

Are you talking about IPv6?
I use single IPv4 DDNS url to my router and OpenVPN and can access all 10+ devices with the same IP addresses localy or remotely.

Have you tried dnsomatic?

I use DynDns myself. There it is possible to put following in 'Host Name:' field of my Asus router (AC-3200):
hostname1.dyndns.org,hostname2.dyndns.org
Works out to make both host names resolve to external IP of router. If this works with NoIp, I do not know. Might be worth a try. I.e., using the comma ',' between host names.

Manage this from your DNS provider, not on the router...

We get this question frequently...

No - don't do that - esp. with Dyn - easier way is managing your domain records at Dyn directly...

(disclosure - I am a DynDNS customer, and have my own domain, and I point stuff all over the place for my domain - they have some really good help files for self-help, and their support team can help you sort out the odd-stuff)

Your ddclient associates your IP to the DNS Provider account - and there - you manage domains, hosts, IP's, etc...

You can have one domain pointed at 20 IP's, or 20 domains pointed at 1 IP, this is how DNS works - dynamic or not...

DNS is a database - and it's relational...

I'll not disagree that your way might be more correct, especially if scaling with more IP's and host names. But the ',' method has its uses for only a few names. It is part of DynDns's update API (look Field / hostname):
https://help.dyn.com/remote-access-api/perform-update/
Also looks like NoIp's implementation supports it (look Field / hostname):
http://www.noip.com/integrate/request

So as long as the router in question do not mangle/choke on the string given in its host name field. It is a convenient method in some cases.

Though. Without having used NoIp myself, it looks to support groups (no suprise):
http://www.noip.com/support/knowledgebase/how-to-configure-your-no-ip-hostname/
Quote: "Assign to Groups: Groups simplify updating hosts. If you have lots of hosts and want to update them in an effective way create a group! By grouping your hosts you can use this page to update all hosts in your group to a given IP address. If you are an Enhanced or Plus DNS user, you can even create sub-accounts and password protect them."

Not sure if free vs. paid account limits functionality more than said here. You'll have to find out yourself (@bozolino)

You are supposed to encode your host-name before sending request. So that comma (,) will become %2C, and will not affect your query string.

Agree. It was more a reference to routers I have worked with in the past who have had its own limiting validation of host name before encoding the URL. Not accepting ',' at all. Or just cutting out the comma and everything after. I guess group logic could save the day then.
