If you want to merge I suggest using GeoIP_name_by_ipnum() because
this can read AS database, ISP base, Organization base and Domain
base.

GeoIP_org_by_ipnum() is the old function of GeoIP, this is the one
used by the official example:


>From GeoIP official API:
http://geolite.maxmind.com/download/geoip/api/c/GeoIP-1.4.7.tar.gz

GeoIP-1.4.7\apps\geoiplookup.c
else if (GEOIP_ORG_EDITION == i || GEOIP_ISP_EDITION == i) {
org = GeoIP_org_by_ipnum(gi, ipnum);
==
if (GEOIP_DOMAIN_EDITION == i) {
domain_name = GeoIP_name_by_ipnum(gi, ipnum);


However, GeoIP.h states that GeoIP_org_by_ipnum is deprecated, but
paradoxally there are still recommending it in code examples.

I didn't see official code using GeoIP_name_by_ipnum for ISP but it
seems to be ok.


In:
static char *
ngx_http_geoip_city(ngx_conf_t *cf, ngx_command_t *cmd, void *conf)

should add (for cleanup)

+ if (gcf->organization) {
+ GeoIP_delete(gcf->organization);
+ }
+
