Bash partially highlights IP address

[exploide]

Describe the bug

When highlighting Bash code, the first octet of an IPv4 address is colored (like a number). The last three octets are not highlighted. This looks a bit odd. When highlighting the code in Fish syntax, it is not colored, so I assume it's an issue with the bash lexer parsing literal numbers.

To Reproduce

Just try the following on the Chroma playground. Language Bash, Style monokai.

ping 192.0.2.1
