239-239: LGTM! Consider enhancing the flag documentation.The new
-specify-ipflag is well-integrated into the input options group. However, the description could be more detailed to help users understand:
- The specific use cases (e.g., scanning through reverse proxies, WAFs)
- Examples of valid input formats
- Interaction with other input methods (list, stdin)
Consider updating the flag description to be more comprehensive:
-flagSet.BoolVarP(&options.SpecifyIP, "specify-ip", "ip", false, "scan the specified IP address (items provided as IP,URL)") +flagSet.BoolVarP(&options.SpecifyIP, "specify-ip", "ip", false, "scan the specified IP address (format: IP,URL). Useful for scanning through reverse proxies/WAFs or when target resolution is not desired")

The addition of the SpecifyIP field to the ipOptions struct is clean and well-aligned with the existing boolean fields.

239-241: Verify interaction with other IP-related flags.
The new -specify-ip flag is added alongside other IP-related flags. Please ensure proper interaction between these flags.
✅ Verification successful
Let me analyze the interactions between these IP-related flags based on the code snippets found.
The search results show clear handling of these flags in the codebase:
-
In
pkg/input/provider/list/hmap.go, the flags are used in a mutually compatible way:SpecifyIPhandles custom IP,URL pairs with proper parsingScanAllIPsperforms DNS lookups to get all associated IPsIPVersionis used to filter IPs (4/6) during processing
-
In
internal/runner/options.go, there's proper default handling for IP versions where IPv4 is the default if none specified.
Let me verify one more aspect to ensure there are no conflicting conditions between these flags.
Let me try one more search to specifically look for any validation logic between these flags.
Based on the code analysis, I can now provide a final response:
The IP-related flags are properly implemented with compatible interactions
The codebase shows well-structured handling of these flags:
SpecifyIPandScanAllIPsare processed independently in separate code blocksIPVersionworks as a filter on top of either flag's behavior- Default IPv4 is properly set when no IP version is specified
- No conflicting validation rules or mutually exclusive conditions were found

🛠️ Refactor suggestion
Add IP address validation.
The code should validate that the specified IP address is in a valid format before using it.
Example implementation:
+func isValidIP(ip string) bool {
+ return net.ParseIP(ip) != nil
+}
if i.ipOptions.SpecifyIP {
valueParsed := strings.SplitN(value, ",", 2)
if len(valueParsed) == 2 {
+ ip := strings.TrimSpace(valueParsed[0])
+ if !isValidIP(ip) {
+ gologger.Warning().Msgf("Invalid IP address specified: %s", ip)
+ return
+ }
metaInput := contextargs.NewMetaInput()
metaInput.Input = strings.TrimSpace(valueParsed[1])
- metaInput.CustomIP = strings.TrimSpace(valueParsed[0])
+ metaInput.CustomIP = ip
i.delItem(metaInput)
return

Thanks for your contribution @p-l- ! :) |
Proposed changes
This PR adds a
-specify-ipwhich changes the expected target formet to<IP address>,<URL>.It makes it easier to scan one host with a given hostname, that could be either non-resolvable / internal, or that could resolve to a reverse-proxy or WAF and we have found the origin.
The format is compatible with zgrab2.
