DNS does not store MAC addresses, just IP addresses.   Perhaps you're
thinking, instead, of clearing the ARP cache?

I have a feeling that this may be a non-issue.  The time it takes to
restore libraries (at least on my system) is MUCH longer than the ARP
cache lasts, therefore as long as you take the old interface down, and
bring the new one up before doing the restore, this should be a non-issue.
Of course, your mileage may vary...  different machines have different ARP
limitations.

In the "UNIX-type APIs" category of the system APIs there are some SNMP
APIs.  I've never used them, but they're probably whay you're looking for.
