It would be far easier if you posted the IP address here, but having said that, here goes...

Sure, your ISP can insert those for you. Note that ARIN (?? Shouldn't your IP be from APNIC?) whois database usually has nothing to do with DNS. > Q: Who is required to provide reverse lookups...my own DNS server? or > does my ISP have to do something in this? like he had to provide an ARIN If you have just one IP address, your ISP wouldn't have delegated it to you. Hence, it is your ISP who should add the reverse DNS entry. Typically, for a.b.c.d, the reverse DNS should be the guy/lady who administers the DNS server returned by: dig c.b.a.in-addr.arpa soa eg: For 32.97.182.141, we find: [EMAIL PROTECTED] root]# dig 182.97.32.in-addr.arpa soa ;; ANSWER SECTION: 182.97.32.in-addr.arpa. 86400 IN SOA master.us.prserv.net. domreq.att.com. 1101161371 14400 7200 604800 86400 You can query master.us.prserv.net to get a reverse entry for the above IP address (if any). Note that the next entry in the SOA record (here domreq.att.com) is actually the email address of the DNS server administrator - just replace the first period with an '@' sign - [EMAIL PROTECTED] (Not every ISP has a mailbox setup at that address or has staff monitoring it, though). Following this through, we get: [EMAIL PROTECTED] root]# dig @master.us.prserv.net. 141.182.97.32.in-addr.arpa ptr ;; ANSWER SECTION: 141.182.97.32.in-addr.arpa. 86400 IN PTR e1.ny.us.ibm.com. > entry so anyone looking up the IP can get my organization name!

I actually don't understand delegation? especially for a single > IP/multiple domains? How its done & who does it in such a case. Delegation is very simple - for forward zones, you have your domain registrar sending your nameserver info to the TLD DNS servers, who will delegate the zone to you. Similarly, for reverse zones, it should be your "IP registrar" - ie, ARIN or APNIC or RIPE or whatever - who delegates (has already delegated) the zone to your ISP, who can possibly delegate it further to you. Any number of delegations are possible - you can delegate subdomains on your forward zone to someone else (say, to a branch office) and they will have full control on what entries they maintain in the subdomain, without having to bother you for every add/remove/change request. You delegate simply by having a separate SOA record for the subdomain in question. > Q: Whois lookup of my .in domain queries ncst whois server, which simply > does not respond.

I think they try to keep that damn server down as much time as possible. > Hope someone will take the trouble to give me some guidance in addition > to some pointers to some reading material on what is involved in doing > what I have explained above. DNS and Bind, whatever is the latest edition. Though its name mentions bind, it is probably the single most authoritative book you can have on DNS administration. Master the dig command. Some of the tools on www.dnsstuff.com are pretty nifty, too. If all else fails, you can post here too. :) > PS: LIH list does not send my own mail to me, though replies come to me. > How do I change this behaviour?
