Hi, I have noticed sometimes the website take a while to load, although most of the time its all fine. It seems to depends where I am. Anyway, doing some speed measurements in google Chrosme seeing where time gets taken up, all speeds on there look good. I also use WebPageTest.org, sometimes a page load time could be 5 seconds. There is a lot of things outside of the website that get loaded, its just vBulletin which take up quite a few resources, hence the dedicated server. Anyway, not to worry about all that, just wanted to give a bit of background.

I used something called Dynatrace.com done a speed test on the website.

As you can see the DNS took 1.4 seconds. Not good at all.

The time in web page tests, the DNS time is far better, I've been trying different zones and the DNS look up appears to be fine. HTML page serves in 384ms including DNS lookup.

After seeing the Dynatrace.com report I wanted to investigate my DNS setup. Is it correct etc.. Its on the eUKHost dedicated server. I set them up myself, mainly copying from my previous website that was hosted on a Windows Server. So as I have had an input on the DNS settings I am doubting my ability to get it correct.

So I tried a 'Domain Health Report' tool from Ultratools.

Many warmings.

Name servers have the same NS record list as parent zone

WARNING

The NS records from ns.solent-renegades.co.uk are different from the parent zone.

The NS records from ns2.solent-renegades.co.uk are different from the parent zone.

Description: Check that authoritative name servers present the same name server list as the parent zone. For more information, please consult the following RFC's: RFC 1034, RFC 1035

Glue records are consistent between the parent zone and authoritative name servers

WARNING

The glue record ns2.solent-renegades.co.uk/5.77.47.66 did not match an IP from an authoritative server.

Description: Check that the addresses provided by the authoritative name servers for the glue records match those from the parent zone. For more information, please consult the following RFC's: RFC 1912

Name servers have reverse DNS entries

WARNING

Reverse DNS entries were found for 5.77.47.66 but did not point back to the name server ns.solent-renegades.co.uk.

Description: Reverse DNS records allow for translation of an IP address back to a domain name. If reverse DNS entries are not present, or do not point back to the nameserver host, reverse lookups may not be possible or accurate. It is common practice for Internet applications, such as email services seeking to identify SPAM, to validate the origin of a request using a reverse lookup as a check and balance for the server in question. For more information, please consult the following RFC's: RFC 1033

SOA serial numbers have valid format

WARNING

The serial value of 1413833187 does not match the recommended yyyymmddxx format.

Description: Check the SOA serial number from each authoritative name server for validity. For more information, please consult the following RFC's: RFC 1034, RFC 1035, RFC 1982

SPF record is present

WARNING

TXT records were found containing SPF information. No SPF records were found.

Description: It is considered a best practice to specify an SPF resource record for your domain, or to specify a TXT record with SPF information in it. SPF (Sender Policy Framework) allows a domain owner to explicitly authorize the hosts that are allowed to use its domain name. Receiving mail servers may check the SPF of other domains, to determine from where (if at all) it should be receiving email. E-mail on the Internet can be forged in a number of ways. In particular, existing protocols place no restriction on what a sending host can use as the reverse-path of a message or the domain given on the SMTP HELO/EHLO commands. SPF records are a means of enforcing against such forgery. For more information, please consult the following RFC's: RFC 4408, RFC 1035

Many more... well 14 warnings, perhaps not all that matter. but perhaps clearing up the warnings, it may give me a speed increase. I have edited some of the DNS settings and left it 24 hours, but it doesn't seem clear the warnings.

These are my DNS settings, is there any thing I can tweak to clear the warnings?
