My isp create a deligation to manage reverse my self.

I managed to reverse the first only.

all the others nothing

PTR record for 212.251.11.241: 241.11.251.212.in-addr.arpa.11.251.212.in-addr.arpa

My zone at my name server is 11.251.212.in-addr.arpa

some records are :

240 IN PTR hsl-labs.kraibow.net.
241 IN PTR router.hsl-labs.kraibow.

If your IP range is .240 to .247, your PTR record should look like 247.240/29.11.251.212.in-addr.arpa. Also, what DNS service are you using? I've found that with verisign, it helps to add a completely separate entry for the reverse pointer.

that records i get from my ISP's NS with nslookup.

Non-authoritative answer:
240.11.251.212.in-addr.arpa name = hsl-labs.kraibow.net
240.11.251.212.in-addr.arpa nameserver = ns1.kraibow.net
240.11.251.212.in-addr.arpa
primary name server = ns1.kraibow.net
responsible mail addr = info.hslhost.com
serial = 2010053117
refresh = 3600 (1 hour)
retry = 3600 (1 hour)
expire = 36000 (10 hours)
default TTL = 38400 (10 hours 40 mins)

240.11.251.212.in-addr.arpa nameserver = ns1.kraibow.net

241.11.251.212.in-addr.arpa canonical name = 241.11.251.212.in-addr.arpa.11.251.212.in-addr.arpa

11.251.212.in-addr.arpa nameserver = nsthe.forthnet.gr
nsath.forthnet.gr internet address = 193.92.150.3
nsher.forthnet.gr internet address = 193.92.150.3
nsthe.forthnet.gr internet address = 193.92.110.1
teiresias.forthnet.gr internet address = 194.219.227.2


at 212.251.11.240 its a PTR record and works ok for me.

241.11.251.212.in-addr.arpa.11.251.212.in-addr.arpa
242.11.251.212.in-addr.arpa.11.251.212.in-addr.arpa
243.11.251.212.in-addr.arpa.11.251.212.in-addr.arpa
244.11.251.212.in-addr.arpa.11.251.212.in-addr.arpa
245.11.251.212.in-addr.arpa.11.251.212.in-addr.arpa
246.11.251.212.in-addr.arpa.11.251.212.in-addr.arpa
