I work for Wiseman Lee in East London
Our external IP address shows up as 18.104.22.168 - assigned to London Link (Our current ISP)
Our MX records are mail.wisemanle.co.uk 22.214.171.124 again assigned to london Link
As part of a network reshuffle we are switching to another ISP who will also handle the SMTP feed etc...
How would I proceed with this and what exactly is invloved
Will we be issued another IP address from our new ISP (This wll need to go into my firewal)
