Need to use dnscmd to modify the ttls of a list of records..

Question

Hi,

I have a list of records that all need their individual TTLs modified. I can't seem to find a way with this odd syntax to do so, however. Any recommendations? Would I have to delete them all and then re-add after with the correct settings?

I can't seem to find a "modifyrecord" option unfortunately :(

The question as written doesn't make sense - what "odd syntax", for example? What DNS software?

In any event, the standard way to change the DNS records on a running server is to use DNS Dynamic Updates (RFC 2136).

If on the other hand you're talking about Microsoft's dnscmd utility then:

1. this should probably be on http://serverfault.com/
2. with dnscmd you do indeed have to delete the record and add it again
