Migrating External DNS to host provider and had a question on SOA

Hello EE,

We currently have a External DNS server on our network and are in the process of migrating over to Network Solutions.
My question is I know I can setup CNAMEs and A records as we have on our DNS server, but we also have a SOA and I'm unsure of the use of this or requirement.  Do I need to set this up with Network Solutions as I don't see how?  Do I need it configured in house still so it knows where my DNS is externally?

You need registry to point to server that knows your DNS zone starting from SOA
For such move first step is to set SOA low on hosted DNS server and wait 2 old long SOAs for new to kick in.

If your internal and external DNS zones are separate (split DNS), then you don't need to worry about preserving the SOA records for your external zone on your internal DNS servers. IOW, there should be SOA records on your internal servers only for your internal network/domain pointing to the internal DNS servers that handle name resolution for the internal domain. (Did I say "internal" enough times in that sentence? :-)

Since you're talking about migrating to NetSol, I am assuming you're talking about "Internet DNS" and not the "Active Directory DNS" the earlier respondent referenced.

The SOA record in Internet DNS is the "start of authority" record. It is essentially a statement that says that THIS server can respond authoritatively for THIS domain. In a way, it is what helps you make a "sub-domain"....

The format and values that go into the SOA record are well defined, but perhaps the one that is the most important is the serial number/timestamp, as this allows proper synchronization of data between DNS servers.
