The LUA record geoiplookup function is not documented at all. We should fix that.

geoiplookup(ip, attr) where attr is:

  enum GeoIPQueryAttribute {
    ASn, // 0
    City, // 1
    Continent, // 2
    Country, // etc
    Country2,
    Name,
    Region,
    Location
  };

geoiplookup('1.1.1.1', 'Beijing') to use it ?

geoiplookup('1.1.1.1', 1) to get the City for 1.1.1.1

got it

var: bestwho can i use geoiplookup(bestwho, 1)?

geoiplookup(bestwho:toString(), 1) should work, I believe

how to print this result?A; local city=geoiplookup(bestwho:toString(), 1); print(city)
this right?

sure, that should print to stdout on the process. Alternatively, return it in a TXT record. But this is a support question so we'll take that to IRC.

it is so sorry;
";local city=geoiplookup(who:toString(),1); print(who,bestwho,city) return '1.1.1.1' "
this is not work, i print is unkown

i print(who, betwho,city)
this is result 172.253.4.4 114.242.250.0 unknown

i use this ips https://geolite.maxmind.com/download/geoip/database/GeoLite2-City.tar.gz,
but it is print unknown
