NOTE: Si2 External IP Address Changes
* Recently, Si2 switched network service providers and subsequently, all of its external IP addresses.
* Email reflectors are used by our many Production and Open Standards collaborative research/development working groups.
* If your company uses access control lists to manage email traffic, and you send emails via the Si2 reflector list system, then the following information will be relevant to you.
CONTACT YOUR IT DEPARTMENT TO VERIFY YOUR CURRENT OR FUTURE STATUS:
After the Si2 IP changes, reflector list messages that previously appeared as email coming from 18.104.22.168 will now show as email coming from 22.214.171.124. Any access control lists that reference the old Si2 IP (126.96.36.199), will need to be updated to the new Si2 IP (188.8.131.52) in order to restore previous functionality. Additionally, make sure that your company IT has Si2 white listed!
