# You can specify the IP database by yourself [IP-API.com here], if not specified, LeoMoeAPI will be used
nexttrace --data-provider ip-api.com
## Note There are frequency limits for free queries of the ipinfo and IPInsight APIs. You can purchase services from these providers to remove the limits
##      If necessary, you can clone this project, add the token provided by ipinfo or IPInsight and compile it yourself
##      Fill the token to: ipgeo/tokens.go

## Note For the offline database IPInfoLocal, please download it manually and rename it to ipinfoLocal.mmdb. (You can download it from here: https://ipinfo.io/signup?ref=free-database-downloads)
##      Current directory, nexttrace binary directory and FHS directories (Unix-like) will be searched.
##      To customize it, please use environment variables,
export NEXTTRACE_IPINFOLOCALPATH=/xxx/yyy.mmdb
##      For the offline database Ip2region, you can download it manually and rename it to ip2region.db, or let NextTrace download it automatically
## Please be aware: Due to the serious abuse of IP.SB, you will often be not able to query IP data from this source
## IP-API.com has a stricter restiction on API calls, if you can't query IP data from this source, please try again in a few minutes

# The Pure-FTPd IP database defaults to using http://127.0.0.1:2060 as the query interface. To customize it, please use environment variables
export NEXTTRACE_CHUNZHENURL=http://127.0.0.1:2060
## You can use https://github.com/freshcn/qqwry to build your own Pure-FTPd IP database service

# You can also specify the default IP database by setting an environment variable
export NEXTTRACE_DATAPROVIDER=ipinfo

Example:
nexttrace --data-provider IPAPI.com --max-hops 20 --tcp --port 443 --queries 5 --no-rdns 1.1.1.1
nexttrace -tcp --queries 2 --parallel-requests 1 --table --route-path 2001:4860:4860::8888
