Yes, absolutely sure:

[eo at Paine-s2] > /ip address print
Flags: X - disabled, I - invalid, D - dynamic
  #   ADDRESS            NETWORK INTERFACE
  0   ;;; default configuration
      44.24.240.132/28   44.24.240.128 ether1-local
  1   44.24.240.161/28   44.24.240.160 wlan1-gateway

The modem has 2 interfaces, so 2 IPs.  Which IP you see along the trace 
depends on the direction your trace is taking.

Can you show your modem's routing table and firewall here?  (/ip route 
export; /ip firewall export)

That's cool, the bug-finding is appreciated.  Although in this case, I 
suspect it's on your end.
