Hello forum people and helpers!

I'm struggling quite a bit here on how to setup DDNS on a sub domain only. I work as IT Engineer but Networking has never been my strong suite and I'm currently transitioning into a Project Management role away from IT Systems Support, so please bear with me.

Anyway onto my issue. I'll be using

google.com

as an example here. Say I own

google.com

and I want it to point to main service or off site host, a search engine at IP

5.5.5.5

. Then say I'm personally hosting

email.google.com

at home with an IP of

70.70.70.70

. I want allow people to connect to my storage site on a different port at

storage.google.com

that would be pointing to

70.70.70.70:49000

.

My current Registar doesn't allow me to point custom Name Servers to sub domains so that option doesn't work for me unfortunately. The current Name Servers I have set are

ns1.dynu.com

through

ns12.dynu.com

though.

I have setup two DDNS services on Dynu, one for each domain (

google.com

and

email.google.com

), pointing at the IP's I need them to resolve too. I have then setup a SRV record on

google.com

as follows:

Node Name: storage
Type: SRV
Port: 49000
Target: email.google.com

When I run a MXToolbox SRV lookup for

storage.google.com

I get "DNS Record not found" from ns#.dynu.com and then running a DNS check on the same site, it pulls the IP of

google.com @ 5.5.5.5

. Did I configure something incorrect here or am I just not understanding how the routing is working.
