Abstract

Conformément à des modes de réalisation, la présente invention concerne un procédé de traitement de nom de domaine, un appareil, un dispositif électronique et un support de stockage. Le procédé comprend les étapes suivantes : lorsque l'on détecte qu'une demande de service réseau a besoin d'être effectuée, acquérir un nom de domaine requis pour réaliser la demande de service réseau ; vérifier si une adresse IP valide correspondant au nom de domaine est mémorisée, ladite adresse IP valide étant une adresse IP correspondant au nom de domaine et obtenue historiquement par résolution sur la base de HTTPDNS ; et si une adresse IP valide correspondant au nom de domaine est trouvée, générer ensuite une demande de service réseau sur la base de l'adresse IP valide trouvée. De cette manière, lors de la réalisation d'une demande de service réseau, une adresse IP mémorisée localement peut être directement utilisée pour réaliser la demande de service, ce qui permet d'éviter le problème de détournement de nom de domaine provoqué par l'utilisation d'une résolution de nom de domaine directement ainsi que d'impact sur l'efficacité de demande de service en raison d'une défaillance de résolution de nom de domaine.
