If you enable network name resolution and the IP address resolves to a host
name, you will more easily see the difference.  But even without resolving to a
host name, the difference is illustrated below:

Without network name resolution enabled:
ip.src == 67.228.110.120
ip.src_host == "67.228.110.120"

With network name resolution enabled:
ip.src == 67.228.110.120
ip.src_host == "www.wireshark.org"

The format expected for the first is an IP address and the format expected for
the second is a character string.
