Falling foul of reverse lookup

I'm not sure where it all falls apart, the symptoms are that 192.96.32.140
cannot be reverse-mapped to its (many) PTR values.

As a result, I can neither submit change request confirmation for CO.ZA
domains, nor reach support@... for assistance.

A bit of a pain, as I need to update the nameservers, a few domains
have fallen off the edge of the world since the last valid nameserver
has been retired.

Sigh!

Re: Falling foul of reverse lookup

HI,

Looks like flu.ff.co.za is off the air, but mumble.proxima.alt.za is
providing its 23 PTR records for  192.96.32.140

get the reverse sorted then the rest shouldn't be a problem

flu.ff.co.za is refusing to answer. Perhaps it believes that it is no 
longer authoritative for the zone:

At first read, I thought you expected me to drop some reverse entries, but
I guess I ought to get flu.ff (and others) to be authoritative instead.

Also, I'll need to dig up the reason why mumble restricts packet size.
Might be that its OS is a tad old, fixing that ain't an option.
Making sure that it handles TCP requests ought to be possible, though.

Thanks for all the help.

Peering IS <> MWEB

Hi All - I'm interested to hear if anyone on the list has any opinion or 
peferably real-life experience on the quality and reliability of peering 
between IS and MWEB?

I have a customer who might be hosting with MWEB, whose end-users are on 
the IS network and I would like to advise him accordingly.

Please reply to me off-list and I'll endeavour to post a summary back to 
the list for all those interested.

thanks!
regards,
Keith

Re: Peering IS <> MWEB

Hi Keith,

From an MWEB perspective the quality and reliability is great. We peer at JINX and CINX on infrastructure
and network links with ample spare capacity, so we don't foresee any problems.

Jaco Muller
MWEB

*Thanks, Jaco.  What do you make of this response I got: *

"Mweb said (unconfirmed) that they intend to cut all commercial peering in the next year to force the market
to peer freely and privately.
They've already done so with Telkom therefore your traffic between Telkom&  Mweb will go via the
International links."

*Regards,
Keith

Re: Peering IS <> MWEB

Hi Keith,

On 1 November 2010 MWEB cut all COMMERCIAL transit (peering?) relationships in SA. The local peering that
is currently in place between MWEB and other ISPs is settlement free, open peering.

Currently there is no local peering between MWEB and SAIX.

Jaco Muller
MWEB

I guess Keith wants to know if peering between MWEB and IS is 
settlement-free and whether it will thus will remain in place after 1 
November.

I realise that these details are normally not disclosed by ISPs for 
commercial reasons, but it will become public knowledge after 1 November 
anyway...

Regards,
Simeon.
