无法创建 Vpnservice

Question

I am a beginner, I am having trouble using VpnService.

Bad prefixLength Caused by: android.net.VpnService$Builder.addAddress(VpnService.java:496)

The above is the error log.

Builder builder = new Builder();
builder.addAddress("211.147.226.4", 8118);
builder.setSession(getString(R.string.app_name));
builder.setConfigureIntent(pendingIntent);
vpnInterface = builder.establish();

This is my code.

My ip address is ipv4 but I don't know why an error occurred. I need help. Thank you for your help.
