Network unreachable with shared hosting. How to find an external GitLab Runner IPs?

GitLab CI/CD
1

Hello! I’m using shared hosting. They provide SSH access to the www directory for specific IPs.
So I’m trying to configure .gitlab-ci.yml to build and deploy files from GitLab repository.

Here is my pipeline:

deploy:
  stage: deploy
  image: alpine
  before_script:
    - apk add openssh-client
    - eval $(ssh-agent -s) 
    - echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add -
    - mkdir -p ~/.ssh
    - chmod 700 ~/.ssh
  script:
    - scp -o StrictHostKeyChecking=no public.zip $USERNAME@$HOST:$PATH_TO_WWW

Result

...
$ eval $(ssh-agent -s)
Agent pid 13
$ echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add -
Identity added: (stdin) (username@domain.com)
$ mkdir -p ~/.ssh
$ chmod 700 ~/.ssh
$ scp -o StrictHostKeyChecking=no public.zip $USERNAME@$HOST:$PATH_TO_WWW
ssh: connect to host ukrcolor.ftp.tools port 22: Network unreachable
lost connection
Cleaning up file based variables

ERROR: Job failed: exit code 1

Changing IP XXX.XXX.XXX.XX instead of ukrcolor.ftp.tools ($HOST) is not working.
Hosting supports advise to add GitlabCI IP to the list of white IPs but I found no working IPs with Google.
I tried to make an SCP request from my home laptop with static IP and it’s working

Are you using GitLab.com CI, or a self-managed GitLab Runner?

The IP used by the former is not pre-determinable (in other words, it is not static), as the hosts are dynamically allocated through a cloud provisioning service.

I use GitLab CI (free cloud service)
