Subject: CNAME error

Hi Max, thanks for the tip on the PTR record... For me it is not an option asking my ISP to add PTR or NS records for my IP :(
I have a question about the CNAMEs. I checked one of my domains with dnsreport.com, and I have a few non-important warnings:
1) The parent servers are not providing Glue for all my nameservers. I tried many things to remove this warning but I couldn`t. Anyway it says it is normal and it is not a problem.
2) The nameservers on separate class C`s could not be tested. This is related to 1) so I believe it is not a problem.
3) This is an error, in RED: "ERROR: [domain] has CNAME entry [IP]; it is not valid to have a CNAME entry and NS entries for [IP]. See RFC1912 2.4 and RFC2181 10.3 for more information."
This is strange because I haven`t any CNAME assignments on my hosts file. Maybe Smallsrv is adding it by itself?

Not. Server don`t add CNAME record. You may use "nslookup" or "dig" AXFR request to look all records for domain. But for CNAME request,
the server return A record, if CNAME record is absent. I think it is correct.

Cname Isnt like a A record

Cname is short for Custom Name
ie if you have an a record for ns1.exsampel.com than that a record for the ns would be in numbers

now a cname is only used to coverup a arecord so insted of seing a ip number you see ns1.exsampel.com insted of ns1 123.123.112.1
i think i exsplaned the point
