no-dns.as5587.net

Hello

Im using win 2000 dns to run the dns for my domains and email.

Everything works great but when i tracert my mailserver ip
(mail.reach-global.co.uk - 193.243.251.43) it resolves as
no-dns.as5587.net. Why is this? If i ping mail.reach-global.co.uk it
quite happily reaches 193.243.251.43

i have one mx record pointing to mail.reach-global.co.uk and i have the
host (a name record) pointing to 193.243.251.43

Can anyone throw any light on this.

Thanks

There is a PTR record no-dns.as5587.net showing publicly in a reverse
lookup zone. Are you using your own dns server to do the lookups /
tracert? Have you tried using the reachdns.net or bsve.net dns servers?
Do you have CNAME records for dns and/or mail server?

When you tracert to an IP, tracert will perform a reverse lookup on the IP.
Ping only performs the reverse lookup when you use ping -a <IPAddress>

Hello,

I run my own dns servers, but only for my domain names, the servers
themselves use my isp's dns's to resolve names.

I tried adding a pointer record for the mail servers ip address but it
didnt seem to make any difference.

Does this have something to do with they i get the strange resolve?

Your server may be authoritative for your domain name, but unless explicitly
delegated by your ISP, they (the ISP) retains Authority over the reverse
lookup.
