If you change server IP do you need new SSL certificates

My email nightmares continue, my VPS provider has finally given in and is providing me with a new IP for my server. Swapping IP's is pretty straightforward, and I know I will have to update all my DNS records, and there are many, A,AAAA,MX,SPF,DKIM,DMarc, DNSSEC and that for multiple domains that all use the same mail server.

Will I have to provision a new SSL certificate?

I'll answer my own question. Probably should have Googled it first.

SSL certificates are bound to a 'common name', which is usually a fully qualified domain name but can be a wildcard name (eg. *.domain.com) or even an IP address, but it usually isn't.

I hope you do not find they have banned your VPS provider.

MS recently banned all Linodes IP blocks: [theregister.com...]

I was thinking of moving to them because they require manual approval before opening outgoing email ports, and my current IP is blocked from sending to hotmail (but apparently not from Office 365) and I put it down to my current provider being less strict.

I will neither confirm nor deny my use of any particular VPS provider, but suffice it to say that the linked article explains a lot.

Some, not all, and it apparently also affected other ISPs.

I've outsourced all my e-mail and am happier for it.
