Create a JSON config file specifying your list name, provider, and countries (ISO 3166-1 alpha-2 codes):

{
    "list_name": "GeoBlock",
    "provider": "ipverse",
    "countries": [
        "ca",
        "au"
    ]
}

Configuration Fields

Field	Required	Default	Description
list_name	Yes	—	RouterOS address list name
provider	No	ipverse	GeoIP data provider
countries	Yes	—	ISO 3166-1 alpha-2 country codes

Usage

# Build
go build -o routeros-geoip .

# Generate blocklist
./routeros-geoip blocklist.json

# Import on your MikroTik router
/import CountryIPBlocks.rsc

Example Output

The generated .rsc file includes metadata headers and cleans up old entries before importing:

# RouterOS GeoIP Address List: CountryIPBlocks
# Generated: 2026-05-01T22:44:48Z
# Countries: 14
# Total entries: 33210
#
/ip firewall address-list remove [find list=CountryIPBlocks]
/ip firewall address-list
add address=24.152.0.0/19 comment="BRAZIL" list=CountryIPBlocks
add address=45.4.4.0/22 comment="BRAZIL" list=CountryIPBlocks
...

Adding a New Provider

Implement the Provider interface:

type Provider interface {
    Name() string
    FetchCIDRs(countryCode string) ([]string, error)
}

Then register it in NewProvider() in provider.go.
