Transforms.conf not using match_type = CIDR(ip) when searching

mmqt
Path Finder

Leveraging the app ASN Lookup Generator - https://splunkbase.splunk.com/app/3531/ to build a lookup table for that has the following in a lookup table called 'asn'
asn

the transforms.conf file has the following - note I commented out max_matches to test, with or without that line commented it still wont return results

# cat TA-asngen/default/transforms.conf
[asn]
filename = asn.csv
match_type = CIDR(ip)
#max_matches = 1

If I run the following search

| makeresults |eval src="1.0.0.1"| lookup asn ip as src

Nothing is matched, but it should be matched to asn 1335, any thoughts? I feel like I'm doing something wrong

no match

I needed to reboot the instance for it to recognize the input, after the reboot it worked

your query, lookup asn ,not asn.csv

changing the query to asn.csv still does not provide any ip transformation.

how's props.conf?

No props as this is not intended to be an automatic lookup, this lookup is called on demand for any sourcetype that contains an IP.

Props would just remove the need to put in ip as src OUTPUTNEW asn

Which is not the problem I'm trying to solve
