No, that's unrelated, because you're not a customer of the ISP he was 
using.

The problem, as the previous poster said, is that the domain has both a 
CNAME and A record for crm.share-ideas.com.  You can see it if you query 
the authoritative server:

imac:barmar $ dig crm.share-ideas.com a @89.111.171.191 +norec

; <<>> DiG 9.4.2-P2 <<>> crm.share-ideas.com a @89.111.171.191 +norec
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 39132
;; flags: qr aa; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;crm.share-ideas.com.      IN A

;; ANSWER SECTION:
crm.share-ideas.com. 3600  IN A  213.242.225.169

imac:barmar $ dig crm.share-ideas.com cname @89.111.171.191 +norec

; <<>> DiG 9.4.2-P2 <<>> crm.share-ideas.com cname @89.111.171.191 +norec
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 3804
;; flags: qr aa; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 0

;; QUESTION SECTION:
;crm.share-ideas.com.      IN CNAME

;; ANSWER SECTION:
crm.share-ideas.com. 3600  IN CNAME share-ideas.com.
