Hmm.. weird. Private addresses are not routable. which ISP is this?
This is Fewanet (in Pokhara, Nepal) (which is a branch of mos.com.np who
are the authority for .np domain).

Seeing an RFC1918 IP in a traceroute is not uncommon.
For example, several routers in the same facility / the same network might
exchange traffic with each other over a local interface before it then goes
on to another ISP's routers, to finally reach google [unless there's a
connectivity problem or one of the routers on the way has suppressed ICMP,
which will break traceroutes]
I don't understand that. With this ISP, there seems to be no multiple
routes to any destination (atleast until it reaches singtel). All
traffic has to hop through these routers to anywhere on the Internet.
In such a case, which would qualify to be "local interface" ?
1 18.104.22.168 (22.214.171.124) 159.594 ms 199.789 ms 159.896 ms
2 126.96.36.199 (188.8.131.52) 159.802 ms 159.867 ms 159.847 ms
3 192.168.100.5 (192.168.100.5) 159.879 ms 159.921 ms 169.963 ms
4 10.1.191.5 (10.1.191.5) 679.963 ms 669.967 ms 679.900 ms
5 184.108.40.206 (220.127.116.11) 1379.953 ms 709.664 ms 659.939 ms
Again, between hops 3 & 4 there seems to be a big difference in the
round-trip time. Doesn't this mean that that part is a long distance
(may be satellite) link ?
