Is there any way that I can get DHCP table?

[admin]

You can get a list table with IP -> MAC mapping from the ARP table like this:

Code:

macs = {}
lines = io.readfile('/proc/net/arp'):split('\n')

-- skip first and last line
for i = 2, #lines - 1 do
  ip, _, _, mac = unpack(lines[ i ]:gsub('%s+', ' '):split(' '))
  macs[ ip ] = mac
end

log(macs)

Name is a part of DHCP and only the DHCP server / router has this information.
