Jul 12, 2021 · I have tried to execute the ARP -a command in windows. I knew that it is used for mapping IP with MAC addresses. I know the first part there but what about the other two-block? Why is at last ther...

Nov 30, 2010 · At a guess 10.0.0.1 looks like the gateway. Why do you want to find the MAC address for the router you are on? Also, if you cannot connect to a wireless router then you won't be able to find it with this command, there are some other commands you can use to scan for wireless signals. You don't see your computer on there because this is your local arp table, …

Aug 20, 2014 · I eventually figured out that the arp, being a cache table, flushes itself periodically, which is why this method rarely succeeded. The solution is to ping all subnet, but after each ping perform an arp command to see if the IP matches your MAC address, which ensures you not to loose information because of the cache nature of the arp tables.

Dec 11, 2015 · How can I do an inverse ARP lookup in Windows and/or Linux? Say that I have the MAC address of wireless access point which is up and running in the network, but I forgot it's IP address?

@Pacerier - the arp command shows the contents of the Address Resolution Protocol cache, which maps IP addresses to the hardware (mac) addresses . If you haven't contacted the target ip address, then it won't be in the cache. Ping is a simple way to contact it to add it to the cache. You could use any network command, it's just ping is an easy one.

It's "method A". ARP requests for addresses outside the subnet won't be sent at all. The only ARP request will be for the gateway's IP address. If you just set up 192.168.123.1/24 for computer A and do not do anything else, it will have a routing table like this: 192.168.123.0/24 to device eth0 0.0.0.0/0 to gateway 192.168.123.254 device eth0 In such a routing table, the first entry …

Feb 5, 2015 · Dynamic ARP mappings expire automatically after a couple minutes. You'll only have dynamic ARP mappings for devices your machine has sent unicast packets to recently. Do a ping-scan of your subnet (or maybe just ping the subnet-broadcast address or the all-hosts multicast address) and then rerun arp -a. Also note that I believe the arp command has been …

May 18, 2013 · Aside from arp -a, net view /all, or writing a batch script there is no native/built-in command line to do this (at least not that I know of). If you're willing to use a non-native command, I would suggest using Nmap.

Feb 3, 2011 · I am wanting to have a simple command to resolve a MAC address to an IP. Is this even possible? I know the MAC address I am looking to get the IP address.

Jul 19, 2013 · Neighbor Discovery Protocol (NDP) is the IPv6 equivalent of the Address Resolution Protocol (ARP), and on the Unix flavors I'm most familiar with (mostly BSDs) the ndp(8) command is the IPv6 equivalent of the arp(8) command. The command-line options for ndp are often the same as for arp, so ndp -an does exactly what you'd expect.
