    Hello,

    Please see below:

    ## 1st, showing all IPv4/IPv6 addresses configured on fe-0/3/3 and lo0
aarseniev@m7i> show interfaces fe-0/3/3 terse
    Aug 11 18:50:45
    Interface Admin Link Proto Local Remote
    fe-0/3/3 up up
    fe-0/3/3.0 up up inet 198.18.1.0/31
     198.18.2.1/30
     198.18.3.1/25
     inet6 bcde::1/126
     cdef::1/96
     fe80::21b:c0ff:fed8:9060/64

    aarseniev@m7i> show interfaces lo0 terse
    Aug 11 18:50:47
    Interface Admin Link Proto Local Remote
    lo0 up up
    lo0.0 up up inet 7.0.0.7 --> 0/0
     iso 49.0001.0070.0000.0007

    lo0.16384 up up inet 127.0.0.1 --> 0/0
    lo0.16385 up up inet
    
## 2nd, filtering only interested subnet lengths
aarseniev@m7i> show route protocol direct terse | match "/32|/30|/31|/126|/128"

    Not quite what I had in mind but looking at the direct routes is equally good. Thank you

    If you are looking for ip addresses configured on the interface itself, I usually use the following:

     

    root@srx100> show interfaces terse | match inet 
fe-0/0/0.0              up    up   inet     1.1.1.1/24      
sp-0/0/0.0              up    up   inet    
sp-0/0/0.16383          up    up   inet     10.0.0.1            --> 10.0.0.16
fe-0/0/7.0              up    down inet     192.168.3.1/24  
lo0.0                   up    up   inet     127.0.0.1           --> 0/0
lo0.16384               up    up   inet     127.0.0.1           --> 0/0
lo0.16385               up    up   inet     10.0.0.1            --> 0/0
st0.0                   up    up   inet     10.0.0.1/24     
vlan.0                  up    down inet     10.0.1.1/24
