What port does DNS zone transfer use?
The answer is DNS is mostly UDP Port 53, but as time progresses, DNS will rely on TCP Port 53 more heavily.
How do I move a zone from one DNS server to another?
Export the Zones entry to a registry file. Export the Zones entry to a registry file. On the destination DNS server, double-click each registry file to import the Zones subkeys into the registry. Bring the current DNS server down and transfer its IP address to the destination DNS server.
Is port 53 TCP or UDP?
The DNS uses TCP Port 53 for zone transfers, for maintaining coherence between the DNS database and the server. The UDP protocol is used when a client sends a query to the DNS server.
How do I transfer a zone?
In the DNS Manager, right-click the name of the DNS zone and click Properties. On the Zone Transfers tab, click Allow zone transfer. Select Only to the following servers. Click Edit, then in the IP addresses of the secondary servers list, enter the IP addresses of the servers you wish to specify.
What are the three types of zone transfers?
There are three types of zone transfer to consider:
- Full zone transfer.
- Incremental zone transfer.
- AD replication.
What are ports 67 and 68 used for?
Port 67 is for a DHCP client (a destination port of a server), and port 68 is for a DHCP server (a destination port of a client). UDP is used instead of TCP because TCP does not support broadcasting, and 2 of the total DHCP messages use broadcasting (DISCOVER and REQUEST).
What is 445 port used for?
Port 445 is a traditional Microsoft networking port with tie-ins to the original NetBIOS service found in earlier versions of Windows OSes. Today, port 445 is used by Microsoft Directory Services for Active Directory (AD) and for the Server Message Block (SMB) protocol over TCP/IP.
What is the use of port 389?
|Purpose:||Lightweight Directory Access Protocol|
|Description:||LDAP (which is what people call it) is a modern and popular Internet directory access protocol used by many systems and services. Most Windows users will encounter it because Microsoft’s NetMeeting uses and opens the LDAP port 389 while it is running.|
Which tool is used for DNS zone transfer on Windows?
NSlookup is a Windows tool which can be used to initiate a DNS zone transfer that sends all the DNS records to a hacker’s system.
Which tool can be used to perform a DNS zone transfer?
What is DNS zone types?
Broadly speaking, there are five types of DNS zones.
- Primary zone.
- Secondary zone.
- Active Directory-integrated zone.
- Stub zone.
- Reverse lookup zone.
What port does DNS operate on?
Most server programs listen for requests on a “server port”, and client programs (applications) communicate with the server from a random “application port”. A DNS server listens for requests on port 53 (both UDP and TCP). So all DNS requests are sent to port 53, usually from an application port (>1023).
What is the difference between a DNS port and UDP?
UDP messages aren’t larger than 512 Bytes and are truncated when greater than this size. DNS uses TCP for Zone transfer and UDP for name, and queries either regular (primary) or reverse. UDP can be used to exchange small information whereas TCP must be used to exchange information larger than 512 bytes.
What are DNS zones and records?
DNS Zones. A DNS zone is a set of files or records (more precisely, a database of resource record entries) that corresponds to part of the DNS hierarchical namespace. DNS zones are used to delineate which DNS Servers are responsible (authoritative) for resolving name-resolution queries for a given section of the DNS hierarchy.
What is a DNS zone transfer attack?
First of all, a DNS zone transfer is not an actual attack. It’s an information gathering method to facilitate later attacks. In ‘normal’ circumstances, a DNS Zone Transfer is used to copy the zone file (a copy of all DNS names in a zone) from a master DNS server to a slave DNS server.
