I was very pleasantly surprised to receive a personal email from Rick Klau, the Business Product Manager for Blogger today, after my recent blog post below.

He was kind enough to let me know the fixed IP address of ‘Blogger’, so that I may whitelist the blogger server, so that it can interact with our own servers, and continue to update the various blogs hosted on each of our clients websites.

74.125.66.132
74.125.112.132

You can also confirm these addresses by viewing the following page on Google:

Unfortunately though, this will only be a temporary solution for some of our clients, as from March 26th, Blogger will be totally withdrawing it’s support of ftp publishing (ie typing your blog on the blogger platform, and then hitting ‘publish’ so that it appears on your own website):

(An email to this effect, should also be going out to all the email addresses associated with a blogger account using FTP to update their blog on the published server.  I’ve already received about 10 copies this evening at various times during the evening).

They should be releasing a ‘migration tool‘ in the next few weeks, which should help with some of our clients (after a certain amount of reworking).  Unfortunately though, those blogs within a password protected members area, are unlikely to be supported by the new migration tool, so those parts of people’s websites will need to be recoded, and will be interacted with differently in the future.
