Docker cannot get specific ip - docker

Question

Hi I need to assign a specific ip for each docker container for my test automation program called sipp.
I cannot ping or telnet to 192.168.173.215
Here is my configration:
version: '3.3'
services:
sipp4:
build:
context: .
dockerfile: Dockerfile
container_name: sipp4
networks:
mynetwork:
ipv4_address: 192.168.128.2
volumes:
- ./sipp-3.4.1/:/opt/app/sipp
environment:
- "TZ=America/Los_Angeles"
ulimits:
nofile:
soft: 200000
hard: 400000
working_dir: /opt/app/sipp
command: 192.168.173.215:5060 -sf callerCall.xml -inf callerCall.csv -i 192.168.128.2 -aa -m 1 -trace_msg -t un -skip_rlimit -trace_err
networks:
mynetwork:
ipam:
driver: default
config:
- subnet: 192.168.128.0/18
gateway: 192.168.128.200
I am sure about subnet and gateway because I can assign IP with VMware virtual host.
Here is ifconfig inside docker machine (bash)
ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.128.2 netmask 255.255.192.0 broadcast 192.168.191.255

lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 3 bytes 1728 (1.6 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Here is ip
ip a

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
389: eth0#if390: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default
link/ether 02:42:c0:a8:80:02 brd ff:ff:ff:ff:ff:ff link-netnsid 0
inet 192.168.128.2/18 brd 192.168.191.255 scope global eth0
valid_lft forever preferred_lft forever
on the other hand when I use the configuration below, it can ping and access to 192.168.173.215 and auto assigning IP is: 172.17.0.1
sipp1:
build:
context: .
dockerfile: Dockerfile
container_name: sipp1
network_mode: host
volumes:
- ./sipp-3.4.1/:/opt/app/sipp
environment:
- "TZ=America/Los_Angeles"
ulimits:
nofile:
soft: 200000
hard: 400000
working_dir: /opt/app/sipp
command: ./sipp 192.168.173.215:5060 -sf callerCall.xml -inf callerCall.csv -i 172.17.0.1 -aa -m 1 -trace_msg -t un -skip_rlimit -trace_err
When I use the configuration below, its getting ip: 172.18.0.2 and cannot ping anywhere again
sipp4:
