MikroTik

Hi i have CCR 1036 and im route ip on it before i reset config it all my ips Show in ARP but now i add my ip address but all my ips not show on ARP just show ips uses but i want to see all my ip which use or not how can fix it?

It's normal for entries to be missing from the ARP table. They only appear when there has been recent traffic to a mac address.

If you want to know what devices have what static IPs on your network, you don't have to use Mikrotik. Write a script that pings all IPs on your network. Then lookup the arp table on your computer.

I use windows, I write a script such as:

ping 192.168.88.2 -w 10 -n 1
ping 192.168.88.3 -w 10 -n 1
ping 192.168.88.4 -w 10 -n 1

etc. Then arp -a will show all IPs on the network.

I use notepad++ to quickly create the ping script. Go to Edit > Edit Column to insert an incremental list of numbers.

i think cant use this way

i want for example ping 192.168.1.0-192.168.1.255 always repeat again and again

Why is it important for IPs to remain in the ARP table?

If you edit the bridge-local interface, of ether2 if there is no bridge and set the ARP timeout to something very high. Arp entries may still disappear after that timeout, but maybe traffic will be passed at least once per your timeout.

Alternatively, you can set ARP to read-only on your interface. This will cause ARP entries to remain, however your Mikrotik will have to be the DHCP server for your LAN and you'll have to add static IPs to the Arp table manually.

just use ip scan in mikrotik to flood the network.

Hi its important to me becuase i have too many ips and if i set ip on for example a windows server and no body connect to it and that server not connect to other on arp not show and i think i didnt use that ip

i want all my ip in arp if i use it show mac and ip if not show ip with mac 00:00:00:00:00:00

You can enable arp in dhcp server so all your leased ips will be in arp
