If I want to have it such that users can login using a password, but only if they are on a certain IP address, then this plugin can do that? i.e. the password authentication and the IP authentication can be stacked?
Thanks

Check the Moodle logs and extract the IP your user is logging in. It can be something related to the infrastructure that (internal IP, NATs) that prevent arriving the IP you are expecting into Moodle. It the IP is one of you are defining in the plugin settings (or in the IP range), please, come back again with more detail, so that we can manage to see what is happening.
It would be better if you report it into the github.

Actually, this plugin is just for what you are asking for: it's like a manual authentication including the restriction of logging in from a given IP or IP range.
Sorry for the late answer,
Jordi
What I can check from our plugin at https://github.com/SREd-URV/moodle-auth_ip/blob/master/auth.php is that if you state fixed IPs (not ranges), the only problem that may arise is that the REMOTE_ADDR processed in the server side does not match, somehow, to the expected IPs. Could you login as admin from one of those IPs and check the PHP information from the server, and report here the line related to the REMOTE_ADDR. Please, add the confirmation that the shown IP is the corresponding, expected IP.
I'm looking for a plugin that allows guest access if coming from a certain IP and blocks all other guests.
Is this possible with this plugin?
This plugin inherits the behaviour of a "manual" auth plugin, and adding a restriction of the list of allowed IPs.
Consider that "guest" access is something related to the enrolment of a user into a cours (enrol/guest). It is not related to the authentication access. I do not know if there is any other enrolment plugin restricting IP access. I can suggest you to ask it into the tracker as an additional feature form the enrol/guest plugin. Another option is to implement your own enrolment plugin (enrol/ip?) inheriting all from enrol/guest and adding the restriction for the allowed IPs.
There may be another option: set up a course with a guest access, and then restrict all elements be accessible to a given value on a user profile item. I didn't make it so take it as a suggestion.
Regards,
Jordi
