Creating subdomains on Bitrix?

Question

1C-Bitrix

It is necessary to implement subdomains for regions for IM.
Interested in the question, is it possible to create subdomains in a box or is it a separate paid module

Answer 1

If the site is physically the same (the only difference is in the list of products and other characteristics), then you need to set up a server (dns records) so that all subdomains automatically go to the main site, and on the site, depending on the subdomain, change behavior .
Bitrix multisite is not for these tasks.

Answer 2

"multi-site" https://dev.1c-bitrix.ru/learning/course/?COURSE_I...
This is if you need the pages to be different
1 additional domain is included for free, then you need to pay a small penny for each new site.
If not, then mirrors are quite enough for themselves, which is doubtful by the way.
