In some cases, a DHCP server may update a client's A record on its behalf, even if the client did not specifically request this. ĭepending on how the DHCP server is configured, it may perform both A and PTR record updates on behalf of all DHCP clients. The DHCP client will communicate with the authoritative DNS server directly for updating its A record, but the DHCP server updates the DNS server with the client’s PTR record on behalf of the DHCP client. Statically-set clients (static clients) that perform dynamic updates will send updates for both its A record (forward lookup record) and its PTR record (reverse lookup record) to the authoritative DNS server.Ĭlients with dynamically-set network connections (DHCP clients) will communicate with both the authoritative DNS server and the DHCP server for updating A and PTR records. Microsoft Dynamic Updates utilize both DNS and DHCP in order to dynamically update client DNS records.Ĭlients may initiate a dynamic DNS update with either the DNS server or the DNS + DHCP servers, depending on how the client’s network connection is set.
