Hey ! ( TLDR )

So those domains that seemingly magically create new subdomains for users, or companies/sites, after educating my noobish self, are really just virtual linking to the actual folder, or page, belonging to that user/subdomain etc. the code is majority in ur application % htaccess; ive more or less got a hold on that now, but need some kind help or advice on the actual DNS config. I think i got it, but kindly review if all good. Im also happy to share the htaccess/php snippets if needed.

So this app will have main site/landing @ http://myapp.mycompany.com/

and will redirect/create user subfolder once registered:- http://Newuser.Myapp.mycompany.com/
Which is just mycompany.com/~NewUsr/ or whatever routing u might have setup. it may very well be linking to a Login or Homepage, which chks auth, or goes to login

Also need http://data.myapp.mycompany.com/ which is either just a cache/img folder or even later could redirect it to cdn from teh app itself.

(notice in both cases it is a double sub) but apparently it counts as a single. So the word is that i use a Wildcard where the name will vary,

so i need to set up *.myapp.myco.com as a seperate dns record, But now second question, in line with below template, how does dns know to link to DATA.MYAPP.MYCO, and not DATA.MYCO. im guessing its something to do with the @ all over, if you could kindly briefly explain that one, i would be greatful. there is also a http://www.myapp.myco.com

SO as far as i understand it then, the ACTUAL base domain, for this app, or set of DNS is actually pointing to myapp.myco.com, should think of it as single, and not being a subd itself. if so i guess second Q answered then lol

What ive sourced from all over and current work in progress template so far as DNSconfig goes:-

-------------------------------------------------------------------------------
$TTL 14400

@ IN SOA ns1.company.cpom. root.myappp.company.com. (
xxxx
7200
xxx
xxxxxxx
180 )

@ 14400 IN NS ns1.company.com
@ 14400 IN NS ns2.company.com
@ 14400 IN A 123.56.67.890
mail 14400 IN A 123.45.67.890
www 14400 IN A 123.45.67.890
@ 14400 IN TXT "v=spf1 a mx ip4:123.45.67.890 ?all"
data 14400 IN CNAME @
* 14400 IN CNAME @

Thanks bros, will send a something urways for the effort, any small hint or nudge or thumbs up appreciated

Cheers and best,

Hi loomy,

Cant say I am an expert, and I was researching some the same about a year ago. This is found online and noted on a file:

Code:

1. to set up a sub sub domain sub2.sub1.domain.com. 

A) create an A record for sub2.sub1.domain.com and point it to the required IP(the IP of the server hosting the sub sub domain). 

B)For www.sub2.sub1.domain.com to work create another A record for www.sub2.sub1.domain.com and point it to the same IP. This can also be done using a CNAME record.

So, if the server that is going to host your sub sub domain has IP 1.2.3.4, your DNS records should be like this :

1    sub2.sub1.domain.com.         A     1.2.3.4

2   www.sub2.sub1.domain.com.   A     1.2.3.4

To use CNAME records :

1   sub2.sub1.domain.com.                A       1.2.3.4

2   www.sub2.sub1.domain.com.   CNAME   sub2.sub1.domain.com.

the [*.mydomain.com] wildcards really _is_ a wildcard :) – the [*] can consist of numerous subdomains and periods.

(re?)Directing [*.mydomain.com] to [blog.mydomain.com] – and [whatever.blog.mydomain.com] now works.

BUT any non-existant subdomain name to [mydomain.com] now leads to [blog.mydomain.com] instead of  [mydomain.com] !!!     hhhmmmm ........

I have a feeling the whole question is not asked, or, I am not fully understanding, so these may help:

Are you using shared hosting or a VPS ? If shared have a read:

Have a good one!

Thank you mate i think u hit the nail on teh head..

So what u saying is, i should rather use www as teh wildcard, rather tha asterisk ? bit confused on that one, but rest makes perfect sense.

Sorry for late reply .... there is a difference based on the type of hosting ... and I have hit the wall based on my limited experience (I was trained on this as an incidental when I was supporting Raid Boxes and NAS and iSCSI: too long ago !). Blush

My gut says use the * in .htacess .... my brain says flip a coin and watch it stop on its edge. Sad

If you have the solution please post.

If you still have issue suggest you try stackoverflow . com : lots of expertise available there.
