How to verify if an "A" record has actually been added to DNS?

Last Friday late afternoon, I asked the support person to add an "A" record "office" on DNS. But today (Monday) it is still not working as expected.

Is there any way I can verify if this record is actually added on our DNS?

I tried www.network-tools.com | DNS Records | entered the domain name, the "A" record "office" was not there at all. However, I do not trust this tool much because it does not show an "A" record "ftp" with another domain while "ftp" is actually there and working fine.

Any thoughts?
Many thanks!!

Was this change made on your own internal DNS servers ?

If so just run

nslookup office.domain.com <yourdnsserver.server.com>
