I think the MutableExtension() method is the way to go; that will return a
pointer to your extension field, so in this case a pointer
to DNSServerNames. Something like this should work:
i->MutableExtension(dnsServerNames)->add_dnsservers("aaa");
Or you could also do it like this:
DNSServerNames temp;
temp.add_dnsservers("aaa");
*i->MutableExtension(dnsServerNames) = temp;
