What is the dns port number and dhcp port number?

What port is DHCP used?

(DHCP) Dynamic host Configuration Protocol. The Default Port Number is: for DHCP client : 546 for DHCP server : 547

What ports are used by dhcp and the DHCP client?

The port 67 and port 68 are used by DHCP and the DHCP clients.

If you have not modified the default settings for dns on the dhcp client or server what client record or records will the dhcp server update in dns?

A. The PTR resource record.

What services are DHCP and DNS known as?

Infrastructure Services

Describe the integration between DHCP and DNS.?

Traditionally, DNS and DHCP servers have been configured and managed one at a time. Similarly, changing authorization rights for a particular user on a group of devices has meant visiting each one and making configuration changes. DHCP integration with DNS allows the aggregation of these tasks across devices, enabling a company's network services to scale in step with the growth of network users, devices, and policies, while reducing administrative operations and costs.This integration provides practical operational efficiencies that lower total cost of ownership. Creating a DHCP network automatically creates an associated DNS zone, for example, reducing the number of tasks required of network administrators. And integration of DNS and DHCP in the same database instance provides unmatched consistency between service and management views of IP address-centric network services data.Windows Server 2003 DNS supports DHCP by means of the dynamic update of DNS zones. By integrating DHCP and DNS in a DNS deployment, you can provide your network resources with dynamic addressing information stored in DNS. To enable this integration, you can use the Windows Server 2003 DHCP service.The dynamic update standard, specified in RFC 2136: Dynamic Updates in the Domain Name System (DNS UPDATE), automatically updates DNS records. Both Windows Server 2003 and Windows 2000 support dynamic update, and both clients and DHCP servers can send dynamic updates when their IP addresses change.Dynamic update enables a DHCP server to register address (A) and pointer (PTR) resource records on behalf of a DHCP client by using DHCP Client FQDN option 81. Option 81 enables the DHCP client to provide its FQDN to the DHCP server. The DHCP client also provides instructions to the DHCP server describing how to process DNS dynamic updates on behalf of the DHCP client.The DHCP server can dynamically update DNS A and PTR records on behalf of DHCP clients that are not capable of sending option 81 to the DHCP server. You can also configure the DHCP server to discard client A and PTR records when the DHCP client lease is deleted. This reduces the time needed to manage these records manually and provides support for DHCP clients that cannot perform dynamic updates. In addition, dynamic update simplifies the setup of Active Directory by enabling domain controllers to dynamically register SRV resource records.If the DHCP server is configured to perform DNS dynamic updates, it performs one of the following actions:The DHCP server updates resource records at the request of the client. The client requests the DHCP server to update the DNS PTR record on behalf of the client, and the client registers A.The DHCP server updates DNS A and PTR records regardless of whether the client requests this action or not.By itself, dynamic update is not secure because any client can modify DNS records. To secure dynamic updates, you can use the secure dynamic update feature provided in Windows Server 2003. To delete outdated records, you can use the DNS server aging and scavenging feature.

What is the default port number DNS?

DNS uses port 53. DNS queries are generally performed via UDP, and zone transfers are normally done via TCP.

What is the purpose of dnsmasq?

A dnsmaq is a lightweight and easy to configure the DNS forwarder and also the DHCP server. It is aimed to design and provide a DNS and also a DHCP to a small network.

How are bootp and dhcp related?

they both run on the same port number

What is the name of the control panel applet that is used to set dns and dhcp settings?

DNS and DHCP Management are both Administrative Tools. DNS Management is run from the DNS MMC snap in. This can be accessed by using the Run commend, and inputting: dnsmgmt.msc DHCP Management is run from the DHCP MMC snap in. This can be accessed by using the Run commend, and inputting: dhcpmgmt.msc These snap-ins must be installed on the system, or you will be unable to access them.

What TCPIP model layer does DHCP work at?

DHCP is a layer-4 protocol, most commonly transported over UDP. UDP port number 67 is the destination port of a server, and UDP port number 68 is used by the client

Is a dhcp database a distributed database similar to a dns database?

no
