Branding Domain Verification Parameters

[si_jdean]

Can someone tell me the actual DNS records to use for domain name verification?

I'm trying to verify our domain name, and it seems like there's incomplete and conflicting information. The instructions in the verification popup give me a domain-level TXT record, OK that's done. Then it says it wants a CNAME to "events-branding.zoom.us," but doesn't give me a subdomain for that CNAME record. If I try to use "events-branding" as the subdomain for the CNAME record, then in the verification failure error message it says my A record was not found. But they didn't tell me to create an A record! And over in a help document, it says to create a different TXT record for a subdomain as well as an A record, but doesn't give me an IP address to point the A record to!

So, could someone who has successfully verified their domain for branding share what DNS records they created?

Welcome to the Zoom Community, @si_jdean.

I assume you’re working from this Zoom Support article:

https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0057580 

In my case, my main web site is GoodClix.com, and I want to use Events.GoodClix.com for the custom domain name. I’ll assume you’re doing the same by using a sub domain of your main domain.  Make the CNAME record for the sub domain name you want to use as custom. In most DNS editors, this is done by adding the CNAME record to just the subdomain name; this is from dnschecker.com, which lists the fully-qualified domain name:

Zoom doesn’t understand that having both CNAME and A records for any domain is technically invalid, and CNAME will take precedence (see this). But I’m guessing their validity-check routine requires both to pass. Use any NSLOOKUP site to get the IP address of events-branding.zoom.us, and put that in the A record for your subdomain. On nslookup.io:

then back on dnschecker:

Do you have your SSL cert yet?

Thanks so much for your response. Two things you said that did it: I misunderstood what I was verifying, I was just using our domain name, not a subdomain. Our domain name obviously already has an A record! The other thing was creating an A record for the subdomain to the IP address for the Zoom events URL. It wouldn't let me add both a CNAME and an A record for the same subdomain, and when I just did a CNAME it didn't take that. Thanks again for your help!

Excellent, @si_jdean.  I’m confused about which record you were actually able to create in your subdomain: CNAME or A Record? Did you pass the verification step?
