A coalition of Internet companies recently announced that they will stop supporting the environments to accommodate domain name (DNS) operators that do not meet the latest standards.
DNS is a system that translates domain names into Internet Protocol addresses that can be processed by devices.
The changes will take place from February 1, 2019, a date called Day of the DNS flag.
Companies say the DNS is unnecessarily slow and inefficient due to efforts to accommodate several systems that do not comply with the DNS standards established two decades ago.
"This change will affect domains hosted on authoritative servers that are not matched either with original DNS standards since 1987, nor with the new EDNS standards of 1999," they said.
Companies that are part of the coalition include Cisco, Cloudflare, Facebook, Google, and Quad9.
Diagram of the DNA of the flag includes a way to test domains for compliance with new standards.
Testing the domains of South Africa's largest hosting and ISPs resulted in an error message for the big player's website – Telkom.
"This domain does not support the latest DNS standards. As a consequence, this domain can not support the latest security features and may be an easier target for network attackers than it needs," warns the website's DNA of the flag.
To find out if organizations are ready for the change, we talked to South Africa's Internet players.
Nishal Goburdhan, an exchange manager for INKS-ZA, said that all INX servers are fully compatible and ready for the DNA of the flag.
"INX nameservers are authoritative not only for online exchange, but also for the government of South Africa (gov.za) and many IXP and community projects in Africa," Goburdhan said.
Teraco's technical manager and NAPAfrica for interconnection and viewing Andrew Owens for MyBroadband said their internal network and DNS is ready.
"Our outgoing DNS services are hosted by Cloudflare, one of the strongest supporters of the movement, and is therefore consistent. Our reverse DNS is hosted internally and was also tested to provide security of 100%," Owens said.
Owens clarified that Teraco does not offer any hosting or networking services to customers in the data center, so customers will be responsible for their readiness for the DNS Flag Day.
Hetzner said that his network and hosting environment is ready for the DNS flag day.
Internet Solutions said that its DNS servers are ready. Its domains and those of the hosts who have hosted them have passed all the tests, says it.
Afrihost said he had anticipated the change and ensured that both his and his clients were not affected.
"We are finalizing our changes, and we are ready for the change. We will closely monitor something unexpected," Afrofost said.
Webafrica CTO Alan Kirthon told MyBroadband that they have completed DNA preparations with a flag and do not expect any surprises.
"Our DNS requirements are mostly predominantly cloudflare, or IS caching," said Kirthon.
The packet clearing package provides secondary DNS services to almost 400 top-level domains.
"The overall global infrastructure of PCH is in full compliance with the proposals of the DNS flag," it says.
A spokesman for MTN, Jackie O'Sullivan, confirmed that their network and hosting environments were ready for the DNA Day of the flag.
"MTN has done its in-depth analysis and does not expect any problems on the big day."
Vodak said he was ready for a DNA with a flag and will meet the deadline of February 1, 2019.
The current Telecom – refused to comment
The current Telecom could not comment on whether their network and hosting environments were ready for the DNA Day of the Flags.
Telcom – No comment
Telkom did not respond to a request for comment on the DNA flag warning.
The company previously told MyBroadband that its systems were updated for key changes and would monitor its DNS environments during the switch.
"Telkom's DNS systems have been updated with new keys, both on SAIX and Telkom Internet," said Telkom spokesman for MyBroadband at the time.
