Answer: when Nat hides the source of IP of an organisation device this is known as
IP masquerading
.
When a range of IP addresses is set aside for client devices and one of these IPs is issued to these devices when they request one this is known as allocation?
When a ‘range of IP addresses’ is set aside for client devices and ‘one of these IPs’ are issued to these ‘devices’ when they request one, this is known as ‘
dynamic allocation
‘.
Which technique is used with Nat where a source port?
Dynamic port forwarding (DPF)
is an on-demand method of traversing a firewall or NAT through the use of firewall pinholes. The goal is to enable clients to connect securely to a trusted server that acts as an intermediary for the purpose of sending/receiving data to one or many destination servers.
What is responsible for resolving an IP to a domain name?
Explanation:
A pointer (PTR) record
is a type of Domain Name System (DNS) record that resolves an IP address to a domain or host name, unlike an A record which points a domain name to an IP address. PTR records are used for the reverse DNS lookup.
Which type of domain name system DNS server performs a full name resolution request?
Which type of Domain Name System (DNS) server performs a full name resolution request?
A recursive name server
performs a full DNS resolution request.
What is the benefit of NAT?
Some benefits of NAT include:
Reuse of private IP addresses
.
Enhancing security for private networks by keeping internal addressing private
from the external network. Connecting a large number of hosts to the global Internet using a smaller number of public (external) IP address, thereby conserving IP address space.
What does NAT stand for?
NAT stands for
network address translation
. It’s a way to map multiple local private addresses to a public one before transferring the information. Organizations that want multiple devices to employ a single IP address use NAT, as do most home routers.
What is another name for NAT overload?
NAT Overload, also known as
PAT (Port Address Translation)
is essentially NAT with the added feature of TCP/UDP ports translation. The main purpose of NAT is to hide the IP address (usually private) of a client in order to reserve the public address space.
Which type of NAT is the most popular?
The most popular type of NAT configuration,
Overloading
is a form of dynamic NAT that maps multiple unregistered IP addresses to a single registered IP address (many-to-one) by using different ports. It’s also known as Port Address Translation (PAT).
Who assigns IP address?
Your IP address is assigned to your device
by your ISP
. Your internet activity goes through the ISP, and they route it back to you, using your IP address. Since they are giving you access to the internet, it is their role to assign an IP address to your device.
What are the two types of DNS?
- DNS stub resolver server.
- DNS recursive resolver server.
- DNS authoritative server.
Which DNS record is used to resolve IP address to a name?
The most common DNS record types are:
Address Mapping record (A Record)
—also known as a DNS host record, stores a hostname and its corresponding IPv4 address. IP Version 6 Address record (AAAA Record)—stores a hostname and its corresponding IPv6 address.
How do I change my domain name to an IP address?
- Enter the new IP address and a subnet mask. …
- Click the Change IP Address button, and then select the IP we just added from the drop-down menu.
- Changing the site’s IP will make it unavailable at its old IP, and should expect it to appear offline for some time.
What are the 2 types of DNS query resolution types?
In general, there are two ways of resolving a host or a domain name to an IP address, using the domain name system –
a Recursive query and a non-Recursive query
. The Recursive query is, when a DNS client directly gets the IP address of a domain, by asking the name server system to perform the complete translation.
What is DNS Example?
DNS, or the Domain Name System, translates human readable domain names (for example,
www.amazon.com
) to machine readable IP addresses (for example, 192.0. 2.44).
