Hello,

I want to list my domains on different Marketplace like Sav, Sedo, DAN etc, but some of them requires adding TXT Record, I want to know how many TXT records I can add in one domain ?

Pls guide.

I actually don't think there is a hard limit.. but each TXT record is stored against a DB. And if you have a million TXT records, I guess your domain registrars will start notice. :) One of my previous hosting companies had a 4000 domain name limit on my DNS. So I suppose some companies do impose some limits, but this information was either not publicly stated or hard to find.

You're only talking about database limits here. Please understand that this is mostly a technical DNS thing.

AWS has a limit of 10,000 DNS records per hosted zone (aka domain name or subdomain), though they can increase the limit on request for an additional charge.

So it sounds like the host dictates the number, so this would apply to TXT records as well.

And especially Amazon / AWS did not follow the standards regarding DNS Flag Day.

Some bad advice here.
My interpreration of what you're saying this is that it depends whether you're talking about what is practicable from a DNS perspective or from a host record storage perspective. Is that correct?

IE. IF you add 10k TXT records you're going to run into problems.

It's about reliability. Yes, you can put lots of things in local DNS, but you also want to be sure that the message gets through, so to say. There are problems with larger DNS packets. There are solutions to this as well (TCP, EDNS*), but still you have to be very conservative. For the fun of it, you may do a search on how many corporate firewalls and home gateways are still blocking port 53/TCP.
