What is the difference between ping scan and ping sweep?

Summary of the Article: What is the difference between ping scan and ping sweep?

Portsweeping is similar to port scanning, as both methods aim to find listening ports on systems. However, the difference lies in the approach: while port scanning involves scanning one system on multiple ports, portsweeping scans multiple systems on the same port.

Questions:

Why would a ping sweep be used?

In computing, a ping sweep is used to establish a range of IP addresses that map to live hosts. This method helps identify which IP addresses are in use and which ones are free.

Is ping sweep called an ICMP scan?

Yes, ping sweep is used to scan a range of IP addresses using ICMP pings. It can also look up the DNS name for each IP address.

Is ARP scan the same as ping sweep?

No, ARP scan and ping sweep serve different purposes. Ping sweep uses ICMP packets and can be routed, while ARP scan detects hosts in LAN networks but does not work across routers or WAN.

How do I stop ping sweeps and port scans?

Ping sweeps can be controlled in your network by using ACL (Access Control Lists). Another method is to allow only limited ICMP commands or messages from your ISP.

What are the three types of port scan?

The three types of port scanning are:

Vanilla: The scanner tries to connect to all 65,535 ports.
Strobe: A more focused scan, looking for known services to exploit.
Fragmented Packets: The scanner sends packet fragments to bypass firewall filters.

What is an example of a ping sweep?

An example of a ping sweep is when you ping many hosts at once within a specific network range. This helps identify the total number of hosts in that network.

How do you use a ping sweep?

To perform a ping sweep from a Microsoft OS command line, type:

for /l %i in (1,1,254) do @ping -n 1 -w 100 <first three octets of host network>. %i

This command will sweep the network and search for hosts, showing the results.

What is ping scan?

Ping scan, also known as ICMP sweep or ping sweep, is a network scanning technique that uses ICMP ECHO requests to communicate with multiple hosts simultaneously. Its goal is to identify which IP addresses map to live hosts.

What does ARP ping scan do?

ARP ping scans are used by penetration testers and system administrators to detect hosts in LAN networks. Nmap optimizes this scanning technique using its own algorithm.

What are the different types of ping scan?

There are four types of ping scan:

ICMP: Uses ICMP ECHO requests to communicate with hosts.
ACK: Uses ACK packets to identify open ports.
SYN: Utilizes SYN packets to establish connections.
UDP: Looks for open UDP ports.

Portsweeping is similar to port scanning. Portsweeping attempts to find listening ports on systems. The difference is that instead of scanning one system on multiple ports, with portsweeping, multiple systems are scanned on the same port.

In computing, a ping sweep is a method that can establish a range of IP addresses which map to live hosts. The classic tool used for ping sweeps is fping, which traditionally was accompanied by gping to generate the list of hosts for large subnets, although more recent versions of fping include that functionality.

Ping Sweep is used to scan a range of IP addresses using ICMP pings. Ping Sweep can scan a range of IP addresses and show which IP addresses are in use and which ones are currently free. Ping Sweep can also look up the DNS name for each IP address using your configured DNS and WINS servers.

So you will see fewer devices respond with Ping Sweep than with ARP Scan. They both have their uses because ARP Scan does not work once it crosses a router to another subnet or WAN. ICMP packets generated by Ping Sweep are routed unless deliberately blocked, even across the internet.

Ping Sweeping can be controlled in your network to a certain limit by using ACL (Access Control Lists). There is another method to prevent ping sweeping by allowing only limited ICMP commands or messages from your Internet Service Provider (ISP).

The Ping Sweep method is used to ping many hosts at once. For example, if there is a network with network ID 192.10. 0.0/24 then it is very simple to identify the total number of hosts there by ping sweeping this network.

To perform a ping sweep:From a Microsoft OS command line, Type for /l %i in (1,1,254) do @ping -n 1 -w 100 <first three octets of host network>. %i. For example, if the host network is 192.168.Press Enter.Observe the results as the command sweeps the network searching for hosts.

Ping sweep, also known as ICMP sweep or a ping scan, is a network scanning technique you can use to find out which IP addresses map to live hosts. In contrast to a single ping, a ping sweep uses ICMP (Internet Control Message Protocol) ECHO requests to communicate with multiple hosts at the same time.

Ping scans are used by penetration testers and system administrators to determine if hosts are online. ARP ping scans are the most effective wayof detecting hosts in LAN networks. Nmap really shines by using its own algorithm to optimize this scanning technique.

The four types of ping methods that Tenable products use are ARP, ICMP, TCP, and UDP.

Commonly hacked TCP port numbers include port 21 (FTP), port 22 (SSH), port 23 (Telnet), port 25 (Simple Mail Transfer Protocol or SMTP), port 110 (POP3), and port 443 (HTTP and Hypertext Transfer Protocol Secure or HTTPS).

If a port is open, it is being used for a particular service or application and is actively listening to requests sent to that application. If the applications using open ports aren't patched well, these ports can be exploited and used for launching attacks.

“Nmap,” which stands for Network Mapper, is the most widely used port scanning tool. A favorite of system administrators, it can be installed on Windows, Linux, MacOS or built from source code.

There are five major types of natural or artificial ports: Inland port, fishing port, dry port, warm water port and seaport. Among all these types of ports, seaports are the largest and busiest type of ports. This is due to the reason that seaport serves both cargoes as well as passengers.

Nmap. This tool is best for port scanning but Nmap can also be used for ping sweeping.

Internet Control Message Protocol (ICMP) requests (Echo, Information, Timestamp, and Subnet Mask) are used to map network topology. Receipt of an ICMP request is classified as a normal, possibly suspicious, or highly suspicious event.

The PRTG ping sweep utility uses a ping command in a looped routine, to access every node on the network.

Launch a ping scan against a network segment using the following command:#nmap -sn <target>-PS/PA/PU/PY [portlist]: TCP SYN/ACK, UDP or SCTP discovery to given ports.-PE/PP/PM: ICMP echo, timestamp, and netmask request discovery probes.-PO [protocol list]: IP protocol ping.

A ping rate under 50 ms is fantastic and is desirable for professional gamers. Twitch affiliates need an even higher ping rate—often in the 15 to 20 ms range.

[/wpremark]

Measured in milliseconds, a ping rate over 150 ms generates noticeable lag that impacts gameplay. Professional gamers consider a ping rate under 50 ms to be ideal.

Commonly targeted TCP and UDP ports include port 53 (DNS), ports 137 to 139 (Windows NetBIOS over TCP/IP), and 1433 and 1434 (Microsoft SQL Server).

[/wpremark]

For instance, blocking ports 139 and 445 (TCP and UDP) will make your network more difficult for attackers to map out the network, and blocking port 31337 (TCP and UDP) will make you more secure from Back Orifice, a hacking tool. Check out this extensive list of ports with their normally associated uses.

Port scanning is not an illegal activity unless someone can prove that it was used intentionally to breach privacy or obtain unauthorized access.

Install a Firewall: A firewall can help prevent unauthorized access to your private network. It controls the ports that are exposed and their visibility. Firewalls can also detect a port scan in progress and shut them down.
