How to create landing pages for new domains

[lopamudra_Chakr]

We would like to have 3 subdomain microsites –
A. Currently exists – go.passageways.com
B. How do we create for –
    b.1. info.onsembleintranet.com

    b.2. info.onboardmeetings.com

You need to

1. create 2 DNS CNAME records
2. create 2 Domain Aliases in Marketo Admin » Integration » Landing Pages » Rules

The CNAME records will be

info.onsembleintranet.com.     86400   IN      CNAME   passageways.mktoweb.com.
info.onboardmeetings.com.      86400   IN      CNAME   passageways.mktoweb.com.

where 86400 is the Time-To-Live (TTL) or caching lifetime of the DNS record. 86400 seconds = 1 day.

Note — because so many people get the terms wrong — the left-hand-side of a CNAME record is the Alias, not the CNAME. So info.onsembleintranet.com is not the CNAME. The CNAME is the right-hand-side, passageways.mktoweb.com.

Thank you so much, that worked!! One more thing - 

I am trying to add a new branded domain but keep getting the error "no cname error".

My IT team created the CNAME record in front of me and is pointing correctly to the right tracking link.
I also got them to create a new alias "visit" and used that for branded domain "visit.example.com" but even that is giving an error

What was the issue at your end and How did you resolve it at your end? any help on this will be very much appreciated!

You'd have to provide the real domain/s you're using so I can look them up.

Don't know what you're referring to here? No issues to resolve on my side.

Thank you for your help! We were able to resolve the issue and everything is working as it should be.
Also the last line in my previous message was an error in typing, sorry for that!
