Hello!
There is one thing I am missing from old "arp" command: "arp -a" used to
give both symbolic name and numeric address (if resolver is working, of
course).
Now, with "ip neigh" I can get only one at the time, so I have to issue
two commands if I want to check if for eg. a host is alive and I don't
know it's IP address (issued by DHCP), but it's name is registered in
(dynamic) DNS. First "ip -r neigh" to see what is the hostname (I don't
like to remember 100's of hostnames, it's easier to ask Linux for a
list), then ping/dig/whatever to resolve that name to IP...
Example output:
Good
# arp -a
name.domain.tld (192.168.188.34) at aa:bb:cc:dd:ee:f1 [ether] on wlan0
Not so good
# ip neigh
192.168.188.34 dev wlan0 lladdr aa:bb:cc:dd:ee:f1 REACHABLE
# ip -r neigh
name.domain.tld dev wlan0 lladdr aa:bb:cc:dd:ee:f1 REACHABLE
I would expect "ip -a neigh" to behave just like "arp -a", but would be
happy with any way to have names and addresses listed together (new
option, combination of options, ...)
Is there any way this could be implemented?
Thank you!
